 In the most simple mode you can turn time series to rows. This means you get a `Time`, `Metric` and a `Value` column. Where `Metric` is the name of the time series.
 
 ### Time series to columns

 This transform allows you to take multiple time series and group them by time. Which will result in the primary column being `Time` and a column for each time series.
 
 ### Time series aggregations

 This table transformation will lay out your table into rows by metric, allowing columns of `Avg`, `Min`, `Max`, `Total`, `Current` and `Count`. More than one column can be added.

 If you have annotations enabled in the dashboard you can have the table show them. If you configure this

 The data section contains the **To Table Transform (1)**. This is the primary option for how your data/metric
 query should be transformed into a table format.  The **Columns (2)** option allows you to select what columns
 you want in the table. Only applicable for some transforms.

 ### Time series to rows

 In the most simple mode you can turn time series to rows. This means you get a `Time`, `Metric` and a `Value` column. Where `Metric` is the name of the time series.
 
 ### Time series to columns
 
-{{< docs-imagebox img="/img/docs/v45/table_ts_to_columns.png" class="docs-image--no-shadow docs-image--center"

+{{< docs-imagebox img="/img/docs/v45/table_ts_to_columns.png" class="docs-image--block" >}}
 
 
 This transform allows you to take multiple time series and group them by time. Which will result in the primary column being `Time` and a column for each time series.
 
 ### Time series aggregations

+{{< docs-imagebox img="/img/docs/v45/table_ts_to_aggregations.png" class="docs-image--block" >}}
 
 This table transformation will lay out your table into rows by metric, allowing columns of `Avg`, `Min`, `Max`, `Total`, `Current` and `Count`. More than one column can be added.
 
 ### Annotations
 
-{{< docs-imagebox img="/img/docs/v45/table_annotations.png" class="docs-image--no-shadow docs-image--center"

 mode then any queries you have in the metrics tab will be ignored.

+Equal returns true iff protocol buffers a and b are equal.
+The arguments must both be pointers to protocol buffer structs.
+
+Equality is defined in this way:
+  - Two messages are equal iff they are the same type,
+    corresponding fields are equal, unknown field sets
+    are equal, and extensions sets are equal.
+  - Two set scalar fields are equal iff their values are equal.
+    If the fields are of a floating-point type, remember that
+    NaN != x for all x, including NaN. If the message is defined
+    in a proto3 .proto file, fields are not "set"; specifically,
+    zero length proto3 "bytes" fields are equal (nil == {}).
+  - Two repeated fields are equal iff their lengths are the same,
+    and their corresponding elements are equal. Note a "bytes" field,
+    although represented by []byte, is not a repeated field and the
+    rule for the scalar fields described above applies.
+  - Two unset fields are equal.
+  - Two unknown field sets are equal if their current
+    encoded state is equal.
+  - Two extension sets are equal iff they have corresponding
+    elements that are pairwise equal.
+  - Two map fields are equal iff their lengths are the same,
+    and they contain the same set of elements. Zero-length map
+    fields are equal.
+  - Every other combination of things are not equal.

+Package proto converts data structures to and from the wire format of
+protocol buffers.  It works in concert with the Go source code generated
+for .proto files by the protocol compiler.
+
+A summary of the properties of the protocol buffer interface
+for a protocol buffer variable v:
+
+  - Names are turned from camel_case to CamelCase for export.
+  - There are no methods on v to set fields; just treat
+	them as structure fields.
+  - There are getters that return a field's value if set,
+	and return the field's default value if unset.
+	The getters work even if the receiver is a nil message.
+  - The zero value for a struct is its correct initialization state.
+	All desired fields must be set before marshaling.
+  - A Reset() method will restore a protobuf struct to its zero state.
+  - Non-repeated fields are pointers to the values; nil means unset.
+	That is, optional or required field int32 f becomes F *int32.
+  - Repeated fields are slices.
+  - Helper functions are available to aid the setting of fields.
+	msg.Foo = proto.String("hello") // set field
+  - Constants are defined to hold the default values of all fields that
+	have them.  They have the form Default_StructName_FieldName.
+	Because the getter methods handle defaulted values,
+	direct use of these constants should be rare.
+  - Enums are given type names and maps from names to values.
+	Enum values are prefixed by the enclosing message's name, or by the
+	enum's type name if it is a top-level enum. Enum types have a String
+	method, and a Enum method to assist in message construction.
+  - Nested messages, groups and enums have type names prefixed with the name of
+	the surrounding message type.
+  - Extensions are given descriptor names that start with E_,
+	followed by an underscore-delimited list of the nested messages
+	that contain it (if any) followed by the CamelCased name of the
+	extension field itself.  HasExtension, ClearExtension, GetExtension
+	and SetExtension are functions for manipulating extensions.
+  - Oneof field sets are given a single field in their message,
+	with distinguished wrapper types for each possible field value.
+  - Marshal and Unmarshal are functions to encode and decode the wire format.
+
+When the .proto file specifies `syntax="proto3"`, there are some differences:
+
+  - Non-repeated fields of non-message type are values instead of pointers.
+  - Enum types do not get an Enum method.
+
+The simplest way to describe this is to see an example.
+Given file test.proto, containing
+
+	package example;
+
+	enum FOO { X = 17; }
+
+	message Test {
+	  required string label = 1;
+	  optional int32 type = 2 [default=77];

+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or

+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and

+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+// Package prometheus provides metrics primitives to instrument code for
+// monitoring. It also offers a registry for metrics. Sub-packages allow to
+// expose the registered metrics via HTTP (package promhttp) or push them to a
+// Pushgateway (package push).
+//
+// All exported functions and methods are safe to be used concurrently unless
+// specified otherwise.
+//
+// A Basic Example
+//
+// As a starting point, a very basic usage example:
+//
+//    package main
+//
+//    import (
+//    	"log"
+//    	"net/http"
+//
+//    	"github.com/prometheus/client_golang/prometheus"
+//    	"github.com/prometheus/client_golang/prometheus/promhttp"
+//    )
+//
+//    var (
+//    	cpuTemp = prometheus.NewGauge(prometheus.GaugeOpts{
+//    		Name: "cpu_temperature_celsius",
+//    		Help: "Current temperature of the CPU.",
+//    	})
+//    	hdFailures = prometheus.NewCounterVec(
+//    		prometheus.CounterOpts{
+//    			Name: "hd_errors_total",
+//    			Help: "Number of hard-disk errors.",
+//    		},
+//    		[]string{"device"},
+//    	)
+//    )
+//
+//    func init() {
+//    	// Metrics have to be registered to be exposed:
+//    	prometheus.MustRegister(cpuTemp)
+//    	prometheus.MustRegister(hdFailures)
+//    }
+//
+//    func main() {
+//    	cpuTemp.Set(65.3)
+//    	hdFailures.With(prometheus.Labels{"device":"/dev/sda"}).Inc()
+//
+//    	// The Handler function provides a default handler to expose metrics
+//    	// via an HTTP server. "/metrics" is the usual endpoint for that.
+//    	http.Handle("/metrics", promhttp.Handler())
+//    	log.Fatal(http.ListenAndServe(":8080", nil))
+//    }
+//
+//
+// This is a complete program that exports two metrics, a Gauge and a Counter,
+// the latter with a label attached to turn it into a (one-dimensional) vector.
+//
+// Metrics
+//
+// The number of exported identifiers in this package might appear a bit
+// overwhelming. However, in addition to the basic plumbing shown in the example
+// above, you only need to understand the different metric types and their
+// vector versions for basic usage.
+//
+// Above, you have already touched the Counter and the Gauge. There are two more
+// advanced metric types: the Summary and Histogram. A more thorough description
+// of those four metric types can be found in the Prometheus docs:
+// https://prometheus.io/docs/concepts/metric_types/
+//
+// A fifth "type" of metric is Untyped. It behaves like a Gauge, but signals the
+// Prometheus server not to assume anything about its type.
+//
+// In addition to the fundamental metric types Gauge, Counter, Summary,
+// Histogram, and Untyped, a very important part of the Prometheus data model is
+// the partitioning of samples along dimensions called labels, which results in
+// metric vectors. The fundamental types are GaugeVec, CounterVec, SummaryVec,
+// HistogramVec, and UntypedVec.
+//
+// While only the fundamental metric types implement the Metric interface, both
+// the metrics and their vector versions implement the Collector interface. A
+// Collector manages the collection of a number of Metrics, but for convenience,
+// a Metric can also “collect itself”. Note that Gauge, Counter, Summary,
+// Histogram, and Untyped are interfaces themselves while GaugeVec, CounterVec,
+// SummaryVec, HistogramVec, and UntypedVec are not.
+//
+// To create instances of Metrics and their vector versions, you need a suitable
+// …Opts struct, i.e. GaugeOpts, CounterOpts, SummaryOpts, HistogramOpts, or
+// UntypedOpts.
+//
+// Custom Collectors and constant Metrics
+//
+// While you could create your own implementations of Metric, most likely you
+// will only ever implement the Collector interface on your own. At a first
+// glance, a custom Collector seems handy to bundle Metrics for common
+// registration (with the prime example of the different metric vectors above,
+// which bundle all the metrics of the same name but with different labels).
+//
+// There is a more involved use case, too: If you already have metrics
+// available, created outside of the Prometheus context, you don't need the
+// interface of the various Metric types. You essentially want to mirror the
+// existing numbers into Prometheus Metrics during collection. An own
+// implementation of the Collector interface is perfect for that. You can create
+// Metric instances “on the fly” using NewConstMetric, NewConstHistogram, and
+// NewConstSummary (and their respective Must… versions). That will happen in
+// the Collect method. The Describe method has to return separate Desc
+// instances, representative of the “throw-away” metrics to be created later.
+// NewDesc comes in handy to create those Desc instances.
+//
+// The Collector example illustrates the use case. You can also look at the
+// source code of the processCollector (mirroring process metrics), the
+// goCollector (mirroring Go metrics), or the expvarCollector (mirroring expvar
+// metrics) as examples that are used in this package itself.
+//
+// If you just need to call a function to get a single float value to collect as
+// a metric, GaugeFunc, CounterFunc, or UntypedFunc might be interesting
+// shortcuts.
+//
+// Advanced Uses of the Registry
+//
+// While MustRegister is the by far most common way of registering a Collector,
+// sometimes you might want to handle the errors the registration might cause.
+// As suggested by the name, MustRegister panics if an error occurs. With the
+// Register function, the error is returned and can be handled.
+//
+// An error is returned if the registered Collector is incompatible or
+// inconsistent with already registered metrics. The registry aims for
+// consistency of the collected metrics according to the Prometheus data model.
+// Inconsistencies are ideally detected at registration time, not at collect
+// time. The former will usually be detected at start-up time of a program,
+// while the latter will only happen at scrape time, possibly not even on the
+// first scrape if the inconsistency only becomes relevant later. That is the
+// main reason why a Collector and a Metric have to describe themselves to the
+// registry.
+//
+// So far, everything we did operated on the so-called default registry, as it
+// can be found in the global DefaultRegistry variable. With NewRegistry, you
+// can create a custom registry, or you can even implement the Registerer or
+// Gatherer interfaces yourself. The methods Register and Unregister work in the
+// same way on a custom registry as the global functions Register and Unregister
+// on the default registry.
+//
+// There are a number of uses for custom registries: You can use registries with
+// special properties, see NewPedanticRegistry. You can avoid global state, as
+// it is imposed by the DefaultRegistry. You can use multiple registries at the
+// same time to expose different metrics in different ways. You can use separate
+// registries for testing purposes.
+//
+// Also note that the DefaultRegistry comes registered with a Collector for Go
+// runtime metrics (via NewGoCollector) and a Collector for process metrics (via
+// NewProcessCollector). With a custom registry, you are in control and decide
+// yourself about the Collectors to register.
+//
+// HTTP Exposition
+//
+// The Registry implements the Gatherer interface. The caller of the Gather
+// method can then expose the gathered metrics in some way. Usually, the metrics
+// are served via HTTP on the /metrics endpoint. That's happening in the example
+// above. The tools to expose metrics via HTTP are in the promhttp sub-package.
+// (The top-level functions in the prometheus package are deprecated.)
+//
+// Pushing to the Pushgateway
+//
+// Function for pushing to the Pushgateway can be found in the push sub-package.
+//
+// Graphite Bridge
+//
+// Functions and examples to push metrics from a Gatherer to Graphite can be
+// found in the graphite sub-package.
+//
+// Other Means of Exposition
+//
+// More ways of exposing metrics can easily be added by following the approaches
+// of the existing implementations.

+// Second, the package provides tooling to instrument instances of http.Handler

+// InstrumentHandlerX, where X describes the intended use of the middleware.
+// See each function's doc comment for specific details.

+# Internal metrics
+
+Grafana collects some metrics about it self internally. Currently Grafana supports pushing metrics to graphite and exposing them to be scraped by Prometheus.
+
+To enabled internal metrics you have to enable it under the [metrics] section in your [grafana.ini](http://docs.grafana.org/installation/configuration/#enabled-6) config file.If you want to push metrics to graphite you have also have to configure the [metrics.graphite](http://docs.grafana.org/installation/configuration/#metrics-graphite) section.

-# jQuery
-
-> jQuery is a fast, small, and feature-rich JavaScript library.
-
-For information on how to get started and how to use jQuery, please see [jQuery's documentation](http://api.jquery.com/).
-For source files and issues, please visit the [jQuery repo](https://github.com/jquery/jquery).
-
-## Including jQuery
-
-Below are some of the most common ways to include jQuery.
-
-### Browser
-
-#### Script tag
-
-```html
-<script src="https://code.jquery.com/jquery-2.2.0.min.js"></script>
-```
-
-#### Babel
-
-[Babel](http://babeljs.io/) is a next generation JavaScript compiler. One of the features is the ability to use ES6/ES2015 modules now, even though browsers do not yet support this feature natively.
-
-```js
-import $ from "jquery";
-```
-
-#### Browserify/Webpack
-
-There are several ways to use [Browserify](http://browserify.org/) and [Webpack](https://webpack.github.io/). For more information on using these tools, please refer to the corresponding project's documention. In the script, including jQuery will usually look like this...
-
-```js
-var $ = require("jquery");
-```
-
-#### AMD (Asynchronous Module Definition)
-
-AMD is a module format built for the browser. For more information, we recommend [require.js' documentation](http://requirejs.org/docs/whyamd.html).
-
-```js
-define(["jquery"], function($) {
-
-});
-```
-
-### Node
-
-To include jQuery in [Node](nodejs.org), first install with npm.
-
-```sh
-npm install jquery
-```
-
-For jQuery to work in Node, a window with a document is required. Since no such window exists natively in Node, one can be mocked by tools such as [jsdom](https://github.com/tmpvar/jsdom). This can be useful for testing purposes.
-
-```js
-require("jsdom").env("", function(err, window) {
-	if (err) {
-		console.error(err);
-		return;
-	}
-
-	var $ = require("jquery")(window);
-});
-```

-//	Implementation Summary
-//
-//	1. Enforce API surface and semantic compatibility with 1.9.x branch
-//	2. Improve the module's maintainability by reducing the storage
-//		paths to a single mechanism.
-//	3. Use the same single mechanism to support "private" and "user" data.
-//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
-//	5. Avoid exposing implementation details on user objects (eg. expando properties)
-//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

-//	3. Use the same single mechanism to support "private" and "user" data.
-//	4. _Never_ expose "private" data to user code (TODO: Drop _data, _removeData)
-//	5. Avoid exposing implementation details on user objects (eg. expando properties)
-//	6. Provide a clear path for implementation upgrade to WeakMap in 2014

- * Attribute not equal selector
- * Positional selectors (:first; :eq(n); :odd; etc.)
- * Type selectors (:input; :checkbox; :button; etc.)

- * Reliable functionality on XML fragments
- * Requiring all parts of a selector to match elements under context

- * Matching against non-elements
- * Reliable sorting of disconnected nodes
- * querySelectorAll bug fixes (e.g., unreliable :focus on WebKit)

-# Contributing to Lodash
-
-Contributions are always welcome. Before contributing please read the
-[code of conduct](https://jquery.org/conduct/) &
-[search the issue tracker](https://github.com/lodash/lodash/issues); your issue
-may have already been discussed or fixed in `master`. To contribute,
-[fork](https://help.github.com/articles/fork-a-repo/) Lodash, commit your changes,
-& [send a pull request](https://help.github.com/articles/using-pull-requests/).
-
-## Feature Requests
-
-Feature requests should be submitted in the
-[issue tracker](https://github.com/lodash/lodash/issues), with a description of
-the expected behavior & use case, where they’ll remain closed until sufficient interest,
-[e.g. :+1: reactions](https://help.github.com/articles/about-discussions-in-issues-and-pull-requests/),
-has been [shown by the community](https://github.com/lodash/lodash/issues?q=label%3A%22votes+needed%22+sort%3Areactions-%2B1-desc).
-Before submitting a request, please search for similar ones in the
-[closed issues](https://github.com/lodash/lodash/issues?q=is%3Aissue+is%3Aclosed+label%3Aenhancement).
-
-## Pull Requests
-
-For additions or bug fixes you should only need to modify `lodash.js`. Include
-updated unit tests in the `test` directory as part of your pull request. Don’t
-worry about regenerating the `dist/` or `doc/` files.
-
-Before running the unit tests you’ll need to install, `npm i`,
-[development dependencies](https://docs.npmjs.com/files/package.json#devdependencies).
-Run unit tests from the command-line via `npm test`, or open `test/index.html` &
-`test/fp.html` in a web browser. The [Backbone](http://backbonejs.org/) &
-[Underscore](http://underscorejs.org/) test suites are included as well.

-established in the code.
-
-- **Spacing**:<br>
-  Use two spaces for indentation. No tabs.
-
-- **Naming**:<br>
-  Keep variable & method names concise & descriptive.<br>
-  Variable names `index`, `array`, & `iteratee` are preferable to
-  `i`, `arr`, & `fn`.
-
-- **Quotes**:<br>
-  Single-quoted strings are preferred to double-quoted strings; however,
-  please use a double-quoted string if the value contains a single-quote
-  character to avoid unnecessary escaping.
-
-- **Comments**:<br>
-  Please use single-line comments to annotate significant additions, &
-  [JSDoc-style](http://www.2ality.com/2011/08/jsdoc-intro.html) comments for
-  functions.
-
-Guidelines are enforced using [JSCS](https://www.npmjs.com/package/jscs):
-```bash
-$ npm run style
-```
-
-## Tips
-
-You can opt-in to a pre-push git hook by adding an `.opt-in` file to the root of
-the project containing:
-```txt
-pre-push
-```
-
-With that, when you `git push`, the pre-push git hook will trigger and execute
-`npm run validate`.

-
-The [Lodash](https://lodash.com/) library exported as a [UMD](https://github.com/umdjs/umd) module.
-
-Generated using [lodash-cli](https://www.npmjs.com/package/lodash-cli):
-```bash
-$ npm run build
-$ lodash -o ./dist/lodash.js
-$ lodash core -o ./dist/lodash.core.js
-```
-
-## Download
-
-Lodash is released under the [MIT license](https://raw.githubusercontent.com/lodash/lodash/4.15.0/LICENSE) & supports [modern environments](#support).<br>
-Review the [build differences](https://github.com/lodash/lodash/wiki/build-differences) & pick one that’s right for you.
-
- * [Core build](https://raw.githubusercontent.com/lodash/lodash/4.15.0/dist/lodash.core.js) ([~4 kB gzipped](https://raw.githubusercontent.com/lodash/lodash/4.15.0/dist/lodash.core.min.js))
- * [Full build](https://raw.githubusercontent.com/lodash/lodash/4.15.0/dist/lodash.js) ([~23 kB gzipped](https://raw.githubusercontent.com/lodash/lodash/4.15.0/dist/lodash.min.js))
- * [CDN copies](https://www.jsdelivr.com/projects/lodash)
-
-## Why Lodash?
-
-Lodash makes JavaScript easier by taking the hassle out of working with arrays,<br>
-numbers, objects, strings, etc. Lodash’s modular methods are great for:
-
-* Iterating arrays, objects, & strings
-* Manipulating & testing values
-* Creating composite functions
-
-## Module Formats
-
-Lodash is available in a [variety of builds](https://lodash.com/custom-builds) & module formats.
-
- * [lodash](https://www.npmjs.com/package/lodash) & [per method packages](https://www.npmjs.com/browse/keyword/lodash-modularized)
- * [lodash-es](https://www.npmjs.com/package/lodash-es), [babel-plugin-lodash](https://www.npmjs.com/package/babel-plugin-lodash), & [lodash-webpack-plugin](https://www.npmjs.com/package/lodash-webpack-plugin)
- * [lodash/fp](https://github.com/lodash/lodash/tree/npm/fp)
- * [lodash-amd](https://www.npmjs.com/package/lodash-amd)

-   * Creates a `lodash` object which wraps `value` to enable implicit method
-   * chain sequences. Methods that operate on and return arrays, collections,
-   * and functions can be chained together. Methods that retrieve a single value
-   * or may return a primitive value will automatically end the chain sequence
-   * and return the unwrapped value. Otherwise, the value must be unwrapped
-   * with `_#value`.
-   *
-   * Explicit chain sequences, which must be unwrapped with `_#value`, may be
-   * enabled using `_.chain`.
-   *
-   * The execution of chained methods is lazy, that is, it's deferred until
-   * `_#value` is implicitly or explicitly called.
-   *
-   * Lazy evaluation allows several methods to support shortcut fusion.
-   * Shortcut fusion is an optimization to merge iteratee calls; this avoids
-   * the creation of intermediate arrays and can greatly reduce the number of
-   * iteratee executions. Sections of a chain sequence qualify for shortcut
-   * fusion if the section is applied to an array of at least `200` elements
-   * and any iteratees accept only one argument. The heuristic for whether a
-   * section qualifies for shortcut fusion is subject to change.
-   *
-   * Chaining is supported in custom builds as long as the `_#value` method is
-   * directly or indirectly included in the build.
-   *
-   * In addition to lodash methods, wrappers have `Array` and `String` methods.
-   *
-   * The wrapper `Array` methods are:
-   * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
-   *
-   * The wrapper `String` methods are:
-   * `replace` and `split`
-   *
-   * The wrapper methods that support shortcut fusion are:
-   * `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
-   * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
-   * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
-   *
-   * The chainable wrapper methods are:
-   * `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
-   * `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,

-     * Creates a `lodash` object which wraps `value` to enable implicit method
-     * chain sequences. Methods that operate on and return arrays, collections,
-     * and functions can be chained together. Methods that retrieve a single value
-     * or may return a primitive value will automatically end the chain sequence
-     * and return the unwrapped value. Otherwise, the value must be unwrapped
-     * with `_#value`.
-     *
-     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
-     * enabled using `_.chain`.
-     *
-     * The execution of chained methods is lazy, that is, it's deferred until
-     * `_#value` is implicitly or explicitly called.
-     *
-     * Lazy evaluation allows several methods to support shortcut fusion.
-     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
-     * the creation of intermediate arrays and can greatly reduce the number of
-     * iteratee executions. Sections of a chain sequence qualify for shortcut
-     * fusion if the section is applied to an array of at least `200` elements
-     * and any iteratees accept only one argument. The heuristic for whether a
-     * section qualifies for shortcut fusion is subject to change.
-     *
-     * Chaining is supported in custom builds as long as the `_#value` method is
-     * directly or indirectly included in the build.
-     *
-     * In addition to lodash methods, wrappers have `Array` and `String` methods.
-     *
-     * The wrapper `Array` methods are:

-     *
-     * The wrapper `String` methods are:
-     * `replace` and `split`
-     *
-     * The wrapper methods that support shortcut fusion are:

-     * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
-     * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`

-     * Creates a throttled function that only invokes `func` at most once per
-     * every `wait` milliseconds. The throttled function comes with a `cancel`
-     * method to cancel delayed `func` invocations and a `flush` method to
-     * immediately invoke them. Provide `options` to indicate whether `func`
-     * should be invoked on the leading and/or trailing edge of the `wait`
-     * timeout. The `func` is invoked with the last arguments provided to the
-     * throttled function. Subsequent calls to the throttled function return the
-     * result of the last `func` invocation.
-     *
-     * **Note:** If `leading` and `trailing` options are `true`, `func` is
-     * invoked on the trailing edge of the timeout only if the throttled function
-     * is invoked more than once during the `wait` timeout.
-     *
-     * If `wait` is `0` and `leading` is `false`, `func` invocation is deferred
-     * until to the next tick, similar to `setTimeout` with a timeout of `0`.

-prepended to the arguments it receives.
-<br>
-<br>
-This method differs from `_.bind` by allowing bound functions to reference
-methods that may be redefined or don't yet exist. See
-[Peter Michaux's article](http://peter.michaux.ca/articles/lazy-function-definition-pattern)
-for more details.

-builds, may be used as a placeholder for partially applied arguments.
-
-#### Since
-0.10.0
-#### Arguments
-1. `object` *(Object)*: The object to invoke the method on.
-2. `key` *(string)*: The key of the method.
-3. `[partials]` *(...&#42;)*: The arguments to be partially applied.
-
-#### Returns
-*(Function)*: Returns the new bound function.

-#### Example
-```js
-var object = {
-  'user': 'fred',
-  'greet': function(greeting, punctuation) {
-    return greeting + ' ' + this.user + punctuation;
-  }
-};
-
-var bound = _.bindKey(object, 'greet', 'hi');
-bound('!');
-// => 'hi fred!'
-
-object.greet = function(greeting, punctuation) {
-  return greeting + 'ya ' + this.user + punctuation;
-};
-
-bound('!');
-// => 'hiya fred!'
-
-// Bound with placeholders.

-
-Creates a debounced function that delays invoking `func` until after `wait`
-milliseconds have elapsed since the last time the debounced function was
-invoked. The debounced function comes with a `cancel` method to cancel
-delayed `func` invocations and a `flush` method to immediately invoke them.
-Provide `options` to indicate whether `func` should be invoked on the
-leading and/or trailing edge of the `wait` timeout. The `func` is invoked
-with the last arguments provided to the debounced function. Subsequent
-calls to the debounced function return the result of the last `func`

-<br>
-**Note:** If `leading` and `trailing` options are `true`, `func` is
-invoked on the trailing edge of the timeout only if the debounced function
-is invoked more than once during the `wait` timeout.
-<br>
-<br>
-If `wait` is `0` and `leading` is `false`, `func` invocation is deferred

-
-An alternative to `_.reduce`; this method transforms `object` to a new
-`accumulator` object which is the result of running each of its own
-enumerable string keyed properties thru `iteratee`, with each invocation
-potentially mutating the `accumulator` object. If `accumulator` is not
-provided, a new object with the same `[[Prototype]]` will be used. The
-iteratee is invoked with four arguments: *(accumulator, value, key, object)*.
-Iteratee functions may exit iteration early by explicitly returning `false`.
-
-#### Since

-#### Arguments
-1. `object` *(Object)*: The object to iterate over.
-2. `[iteratee=_.identity]` *(Function)*: The function invoked per iteration.

-
-#### Returns
-*(&#42;)*: Returns the accumulated value.

-[&#x24C8;](https://github.com/lodash/lodash/blob/4.15.0/lodash.js#L1647 "View in source") [&#x24C9;][1]
-
-Creates a `lodash` object which wraps `value` to enable implicit method
-chain sequences. Methods that operate on and return arrays, collections,
-and functions can be chained together. Methods that retrieve a single value
-or may return a primitive value will automatically end the chain sequence
-and return the unwrapped value. Otherwise, the value must be unwrapped
-with `_#value`.
-<br>
-<br>
-Explicit chain sequences, which must be unwrapped with `_#value`, may be
-enabled using `_.chain`.
-<br>
-<br>
-The execution of chained methods is lazy, that is, it's deferred until
-`_#value` is implicitly or explicitly called.
-<br>
-<br>
-Lazy evaluation allows several methods to support shortcut fusion.
-Shortcut fusion is an optimization to merge iteratee calls; this avoids
-the creation of intermediate arrays and can greatly reduce the number of
-iteratee executions. Sections of a chain sequence qualify for shortcut
-fusion if the section is applied to an array of at least `200` elements
-and any iteratees accept only one argument. The heuristic for whether a
-section qualifies for shortcut fusion is subject to change.
-<br>
-<br>
-Chaining is supported in custom builds as long as the `_#value` method is
-directly or indirectly included in the build.
-<br>
-<br>
-In addition to lodash methods, wrappers have `Array` and `String` methods.
-<br>
-<br>
-The wrapper `Array` methods are:<br>
-`concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
-<br>

-`replace` and `split`

-**Note:** No other characters are escaped. To escape additional
-characters use a third-party library like [_he_](https://mths.be/he).
-<br>
-<br>
-Though the ">" character is escaped for symmetry, characters like
-">" and "/" don't need escaping in HTML and have no special meaning
-unless they're part of a tag or unquoted attribute value. See
-[Mathias Bynens's article](https://mathiasbynens.be/notes/ambiguous-ampersands)
-*(under "semi-related fun fact")* for more details.

-## lodash/fp
-
-The `lodash/fp` module promotes a more
-[functional programming](https://en.wikipedia.org/wiki/Functional_programming)
-(FP) friendly style by exporting an instance of `lodash` with its methods wrapped
-to produce immutable auto-curried iteratee-first data-last methods.
-
-## Installation
-
-In a browser:
-```html
-<script src='path/to/lodash.js'></script>
-<script src='path/to/lodash.fp.js'></script>
-<script>
-// Loading `lodash.fp.js` converts `_` to its fp variant.
-_.defaults({ 'a': 2, 'b': 2 })({ 'a': 1 });
-// ➜ { 'a': 1, 'b': 2 }
-
-// Use `noConflict` to restore the pre-fp variant.
-var fp = _.noConflict();
-
-_.defaults({ 'a': 1 }, { 'a': 2, 'b': 2 });
-// ➜ { 'a': 1, 'b': 2 }
-fp.defaults({ 'a': 2, 'b': 2 })({ 'a': 1 });
-// ➜ { 'a': 1, 'b': 2 }
-</script>
-```
-
-In Node.js:
-```js
-// Load the fp build.
-var fp = require('lodash/fp');
-
-// Load a method category.
-var object = require('lodash/fp/object');
-
-// Load a single method for smaller builds with browserify/rollup/webpack.
-var extend = require('lodash/fp/extend');
-```
-
-## Mapping
-
-Immutable auto-curried iteratee-first data-last methods sound great, but what
-does that really mean for each method? Below is a breakdown of the mapping used
-to convert each method.
-
-#### Capped Iteratee Arguments
-
-Iteratee arguments are capped to avoid gotchas with variadic iteratees.
-```js
-// The `lodash/map` iteratee receives three arguments:
-// (value, index|key, collection)
-_.map(['6', '8', '10'], parseInt);
-// ➜ [6, NaN, 2]
-
-// The `lodash/fp/map` iteratee is capped at one argument:
-// (value)
-fp.map(parseInt)(['6', '8', '10']);
-// ➜ [6, 8, 10]
-```
-
-Methods that cap iteratees to one argument:<br>
-<%= toFuncList(_.keys(_.pickBy(mapping.iterateeAry, _.partial(_.eq, _, 1)))) %>
-
-Methods that cap iteratees to two arguments:<br>
-<%= toFuncList(_.keys(_.pickBy(mapping.iterateeAry, _.partial(_.eq, _, 2)))) %>
-
-The iteratee of `mapKeys` is invoked with one argument: (key)
-
-#### Fixed Arity
-
-Methods have fixed arities to support auto-currying.
-```js
-// `lodash/padStart` accepts an optional `chars` param.
-_.padStart('a', 3, '-')
-// ➜ '--a'
-
-// `lodash/fp/padStart` does not.
-fp.padStart(3)('a');
-// ➜ '  a'
-fp.padCharsStart('-')(3)('a');
-// ➜ '--a'
-```
-
-Methods with a fixed arity of one:<br>
-<%= toFuncList(_.difference(mapping.aryMethod[1], _.keys(mapping.skipFixed))) %>
-
-Methods with a fixed arity of two:<br>
-<%= toFuncList(_.difference(mapping.aryMethod[2], _.keys(mapping.skipFixed))) %>
-
-Methods with a fixed arity of three:<br>
-<%= toFuncList(_.difference(mapping.aryMethod[3], _.keys(mapping.skipFixed))) %>
-
-Methods with a fixed arity of four:<br>
-<%= toFuncList(_.difference(mapping.aryMethod[4], _.keys(mapping.skipFixed))) %>
-
-#### Rearranged Arguments
-
-Method arguments are rearranged to make composition easier.
-```js
-// `lodash/filter` is data-first iteratee-last:
-// (collection, iteratee)
-var compact = _.partial(_.filter, _, Boolean);
-compact(['a', null, 'c']);
-// ➜ ['a', 'c']
-
-// `lodash/fp/filter` is iteratee-first data-last:
-// (iteratee, collection)
-var compact = fp.filter(Boolean);
-compact(['a', null, 'c']);
-// ➜ ['a', 'c']
-```
-
-##### Most methods follow these rules
-
-A fixed arity of two has an argument order of:<br>
-<%= toArgOrder(mapping.aryRearg[2]) %>
-
-A fixed arity of three has an argument order of:<br>
-<%= toArgOrder(mapping.aryRearg[3]) %>
-
-A fixed arity of four has an argument order of:<br>
-<%= toArgOrder(mapping.aryRearg[4]) %>
-
-##### Exceptions to the rules
-
-Methods that accept an array of arguments:<br>
-<%= toFuncList(_.keys(mapping.methodSpread)) %>
-
-Methods with unchanged argument orders:<br>
-<%= toFuncList(_.keys(mapping.skipRearg)) %>
-
-Methods with custom argument orders:<br>
-<%= _.map(_.keys(mapping.methodRearg), function(methodName) {
-  var orders = mapping.methodRearg[methodName];
-  return ' * `_.' + methodName + '` has an order of ' + toArgOrder(orders);
-}).join('\n') %>
-
-#### New Methods
-
-Not all variadic methods have corresponding new method variants. Feel free to
-[request](https://github.com/lodash/lodash/blob/master/.github/CONTRIBUTING.md#feature-requests)
-any additions.
-
-Methods created to accommodate Lodash’s variadic methods:<br>
-<%= toFuncList(_.keys(mapping.remap)) %>
-
-#### Aliases
-
-There are <%= _.size(mapping.aliasToReal) %> method aliases:<br>
-<%= _.map(_.keys(mapping.aliasToReal).sort(), function(alias) {
-  var realName = mapping.aliasToReal[alias];
-  return ' * `_.' + alias + '` is an alias of `_.' + realName + '`';
-}).join('\n') %>
-
-## Placeholders
-
-The placeholder argument, which defaults to `_`, may be used to fill in method
-arguments in a different order. Placeholders are filled by the first available
-arguments of the curried returned function.
-```js
-// The equivalent of `2 > 5`.
-_.gt(2)(5);
-// ➜ false
-
-// The equivalent of `_.gt(5, 2)` or `5 > 2`.
-_.gt(_, 2)(5);
-// ➜ true
-```
-
-## Chaining
-
-The `lodash/fp` module **does not** convert chain sequence methods. See
-[Izaak Schroeder’s article](https://medium.com/making-internets/why-using-chain-is-a-mistake-9bc1f80d51ba)
-on using functional composition as an alternative to method chaining.
-
-## Convert
-
-Although `lodash/fp` & its method modules come pre-converted, there are times
-when you may want to customize the conversion. That’s when the `convert` method
-comes in handy.
-```js
-// Every option is `true` by default.
-var _fp = fp.convert({
-  // Specify capping iteratee arguments.
-  'cap': true,
-  // Specify currying.
-  'curry': true,
-  // Specify fixed arity.
-  'fixed': true,
-  // Specify immutable operations.
-  'immutable': true,
-  // Specify rearranging arguments.
-  'rearg': true
-});
-
-// The `convert` method is available on each method too.
-var mapValuesWithKey = fp.mapValues.convert({ 'cap': false });
-
-// Here’s an example of disabling iteratee argument caps to access the `key` param.
-mapValuesWithKey(function(value, key) {
-  return key == 'a' ? -1 : value;
-})({ 'a': 1, 'b': 1 });
-// => { 'a': -1, 'b': 1 }
-```
-
-Manual conversions are also possible with the `convert` module.
-```js
-var convert = require('lodash/fp/convert');
-
-// Convert by name.
-var assign = convert('assign', require('lodash.assign'));
-
-// Convert by object.
-var fp = convert({
-  'assign': require('lodash.assign'),
-  'chunk': require('lodash.chunk')
-});
-
-// Convert by `lodash` instance.
-var fp = convert(lodash.runInContext());
-```
-
-## Tooling
-
-Use [eslint-plugin-lodash-fp](https://www.npmjs.com/package/eslint-plugin-lodash-fp)
-to help use `lodash/fp` more efficiently.

-     * Creates a `lodash` object which wraps `value` to enable implicit method
-     * chain sequences. Methods that operate on and return arrays, collections,
-     * and functions can be chained together. Methods that retrieve a single value
-     * or may return a primitive value will automatically end the chain sequence
-     * and return the unwrapped value. Otherwise, the value must be unwrapped
-     * with `_#value`.
-     *
-     * Explicit chain sequences, which must be unwrapped with `_#value`, may be
-     * enabled using `_.chain`.
-     *
-     * The execution of chained methods is lazy, that is, it's deferred until
-     * `_#value` is implicitly or explicitly called.
-     *
-     * Lazy evaluation allows several methods to support shortcut fusion.
-     * Shortcut fusion is an optimization to merge iteratee calls; this avoids
-     * the creation of intermediate arrays and can greatly reduce the number of
-     * iteratee executions. Sections of a chain sequence qualify for shortcut
-     * fusion if the section is applied to an array of at least `200` elements
-     * and any iteratees accept only one argument. The heuristic for whether a
-     * section qualifies for shortcut fusion is subject to change.

-     * Chaining is supported in custom builds as long as the `_#value` method is
-     * directly or indirectly included in the build.

-
-
-    This file creates a global JSON object containing two methods: stringify
-    and parse.
-
-        JSON.stringify(value, replacer, space)
-            value       any JavaScript value, usually an object or array.
-
-            replacer    an optional parameter that determines how object
-                        values are stringified for objects. It can be a
-                        function or an array of strings.
-
-            space       an optional parameter that specifies the indentation
-                        of nested structures. If it is omitted, the text will
-                        be packed without extra whitespace. If it is a number,
-                        it will specify the number of spaces to indent at each
-                        level. If it is a string (such as '\t' or '&nbsp;'),
-                        it contains the characters used to indent at each level.
-
-            This method produces a JSON text from a JavaScript value.
-
-            When an object value is found, if the object contains a toJSON
-            method, its toJSON method will be called and the result will be
-            stringified. A toJSON method does not serialize: it returns the
-            value represented by the name/value pair that should be serialized,
-            or undefined if nothing should be serialized. The toJSON method
-            will be passed the key associated with the value, and this will be
-            bound to the value
-
-            For example, this would serialize Dates as ISO strings.
-
-                Date.prototype.toJSON = function (key) {
-                    function f(n) {
-                        // Format integers to have at least two digits.
-                        return n < 10 ? '0' + n : n;
-                    }
-
-                    return this.getUTCFullYear()   + '-' +
-                         f(this.getUTCMonth() + 1) + '-' +
-                         f(this.getUTCDate())      + 'T' +
-                         f(this.getUTCHours())     + ':' +
-                         f(this.getUTCMinutes())   + ':' +
-                         f(this.getUTCSeconds())   + 'Z';
-                };
-
-            You can provide an optional replacer method. It will be passed the
-            key and value of each member, with this bound to the containing
-            object. The value that is returned from your method will be
-            serialized. If your method returns undefined, then the member will
-            be excluded from the serialization.
-
-            If the replacer parameter is an array of strings, then it will be
-            used to select the members to be serialized. It filters the results
-            such that only members with keys listed in the replacer array are
-            stringified.
-
-            Values that do not have JSON representations, such as undefined or
-            functions, will not be serialized. Such values in objects will be
-            dropped; in arrays they will be replaced with null. You can use
-            a replacer function to replace those with JSON values.
-            JSON.stringify(undefined) returns undefined.
-
-            The optional space parameter produces a stringification of the
-            value that is filled with line breaks and indentation to make it
-            easier to read.
-
-            If the space parameter is a non-empty string, then that string will
-            be used for indentation. If the space parameter is a number, then
-            the indentation will be that many spaces.
-
-            Example:
-
-            text = JSON.stringify(['e', {pluribus: 'unum'}]);
-            // text is '["e",{"pluribus":"unum"}]'
-
-
-            text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
-            // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
-
-            text = JSON.stringify([new Date()], function (key, value) {
-                return this[key] instanceof Date ?
-                    'Date(' + this[key] + ')' : value;
-            });
-            // text is '["Date(---current time---)"]'
-
-
-        JSON.parse(text, reviver)
-            This method parses a JSON text to produce an object or array.
-            It can throw a SyntaxError exception.
-
-            The optional reviver parameter is a function that can filter and
-            transform the results. It receives each of the keys and values,
-            and its return value is used instead of the original value.
-            If it returns what it received, then the structure is not modified.
-            If it returns undefined then the member is deleted.
-
-            Example:
-
-            // Parse the text. Values that look like ISO date strings will
-            // be converted to Date objects.
-
-            myData = JSON.parse(text, function (key, value) {
-                var a;
-                if (typeof value === 'string') {
-                    a =
-/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
-                    if (a) {
-                        return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
-                            +a[5], +a[6]));
-                    }
-                }
-                return value;
-            });
-
-            myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
-                var d;
-                if (typeof value === 'string' &&
-                        value.slice(0, 5) === 'Date(' &&
-                        value.slice(-1) === ')') {
-                    d = new Date(value.slice(5, -1));

-
-
-    This file creates a global JSON object containing two methods: stringify
-    and parse. This file is provides the ES5 JSON capability to ES3 systems.
-    If a project might run on IE8 or earlier, then this file should be included.
-    This file does nothing on ES5 systems.
-
-        JSON.stringify(value, replacer, space)
-            value       any JavaScript value, usually an object or array.
-
-            replacer    an optional parameter that determines how object
-                        values are stringified for objects. It can be a
-                        function or an array of strings.
-
-            space       an optional parameter that specifies the indentation
-                        of nested structures. If it is omitted, the text will
-                        be packed without extra whitespace. If it is a number,
-                        it will specify the number of spaces to indent at each
-                        level. If it is a string (such as '\t' or '&nbsp;'),
-                        it contains the characters used to indent at each level.
-
-            This method produces a JSON text from a JavaScript value.
-
-            When an object value is found, if the object contains a toJSON
-            method, its toJSON method will be called and the result will be
-            stringified. A toJSON method does not serialize: it returns the
-            value represented by the name/value pair that should be serialized,
-            or undefined if nothing should be serialized. The toJSON method
-            will be passed the key associated with the value, and this will be
-            bound to the value
-
-            For example, this would serialize Dates as ISO strings.
-
-                Date.prototype.toJSON = function (key) {
-                    function f(n) {
-                        // Format integers to have at least two digits.
-                        return n < 10 
-                            ? '0' + n 
-                            : n;
-                    }
-
-                    return this.getUTCFullYear()   + '-' +
-                         f(this.getUTCMonth() + 1) + '-' +
-                         f(this.getUTCDate())      + 'T' +
-                         f(this.getUTCHours())     + ':' +
-                         f(this.getUTCMinutes())   + ':' +
-                         f(this.getUTCSeconds())   + 'Z';
-                };
-
-            You can provide an optional replacer method. It will be passed the
-            key and value of each member, with this bound to the containing
-            object. The value that is returned from your method will be
-            serialized. If your method returns undefined, then the member will
-            be excluded from the serialization.
-
-            If the replacer parameter is an array of strings, then it will be
-            used to select the members to be serialized. It filters the results
-            such that only members with keys listed in the replacer array are
-            stringified.
-
-            Values that do not have JSON representations, such as undefined or
-            functions, will not be serialized. Such values in objects will be
-            dropped; in arrays they will be replaced with null. You can use
-            a replacer function to replace those with JSON values.
-            JSON.stringify(undefined) returns undefined.
-
-            The optional space parameter produces a stringification of the
-            value that is filled with line breaks and indentation to make it
-            easier to read.
-
-            If the space parameter is a non-empty string, then that string will
-            be used for indentation. If the space parameter is a number, then
-            the indentation will be that many spaces.
-
-            Example:
-
-            text = JSON.stringify(['e', {pluribus: 'unum'}]);
-            // text is '["e",{"pluribus":"unum"}]'
-
-
-            text = JSON.stringify(['e', {pluribus: 'unum'}], null, '\t');
-            // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'
-
-            text = JSON.stringify([new Date()], function (key, value) {
-                return this[key] instanceof Date 
-                    ? 'Date(' + this[key] + ')' 
-                    : value;
-            });
-            // text is '["Date(---current time---)"]'
-
-
-        JSON.parse(text, reviver)
-            This method parses a JSON text to produce an object or array.
-            It can throw a SyntaxError exception.
-
-            The optional reviver parameter is a function that can filter and
-            transform the results. It receives each of the keys and values,
-            and its return value is used instead of the original value.
-            If it returns what it received, then the structure is not modified.
-            If it returns undefined then the member is deleted.
-
-            Example:
-
-            // Parse the text. Values that look like ISO date strings will
-            // be converted to Date objects.
-
-            myData = JSON.parse(text, function (key, value) {
-                var a;
-                if (typeof value === 'string') {
-                    a =
-/^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);
-                    if (a) {
-                        return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],
-                            +a[5], +a[6]));
-                    }
-                }
-                return value;
-            });
-
-            myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
-                var d;
-                if (typeof value === 'string' &&
-                        value.slice(0, 5) === 'Date(' &&

+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of

+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+

+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its

+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+/*
+Package storage provides an easy way to work with Google Cloud Storage.
+Google Cloud Storage stores data in named objects, which are grouped into buckets.
+
+More information about Google Cloud Storage is available at
+https://cloud.google.com/storage/docs.
+
+All of the methods of this package use exponential backoff to retry calls
+that fail with certain errors, as described in
+https://cloud.google.com/storage/docs/exponential-backoff.
+
+Note: This package is in beta.  Some backwards-incompatible changes may occur.
+
+
+Creating a Client
+
+To start working with this package, create a client:
+
+    ctx := context.Background()
+    client, err := storage.NewClient(ctx)
+    if err != nil {
+        // TODO: Handle error.
+    }
+
+Buckets
+
+A Google Cloud Storage bucket is a collection of objects. To work with a
+bucket, make a bucket handle:
+
+    bkt := client.Bucket(bucketName)
+
+A handle is a reference to a bucket. You can have a handle even if the
+bucket doesn't exist yet. To create a bucket in Google Cloud Storage,
+call Create on the handle:
+
+    if err := bkt.Create(ctx, projectID, nil); err != nil {
+        // TODO: Handle error.
+    }
+
+Note that although buckets are associated with projects, bucket names are
+global across all projects.
+
+Each bucket has associated metadata, represented in this package by
+BucketAttrs. The third argument to BucketHandle.Create allows you to set
+the intial BucketAttrs of a bucket. To retrieve a bucket's attributes, use
+Attrs:
+
+    attrs, err := bkt.Attrs(ctx)
+    if err != nil {
+        // TODO: Handle error.
+    }
+    fmt.Printf("bucket %s, created at %s, is located in %s with storage class %s\n",
+        attrs.Name, attrs.Created, attrs.Location, attrs.StorageClass)
+
+Objects
+
+An object holds arbitrary data as a sequence of bytes, like a file. You
+refer to objects using a handle, just as with buckets. You can use the
+standard Go io.Reader and io.Writer interfaces to read and write
+object data:
+
+    obj := bkt.Object("data")
+    // Write something to obj.
+    // w implements io.Writer.
+    w := obj.NewWriter(ctx)
+    // Write some text to obj. This will overwrite whatever is there.
+    if _, err := fmt.Fprintf(w, "This object contains text.\n"); err != nil {
+        // TODO: Handle error.
+    }
+    // Close, just like writing a file.
+    if err := w.Close(); err != nil {
+        // TODO: Handle error.
+    }
+
+    // Read it back.
+    r, err := obj.NewReader(ctx)
+    if err != nil {
+        // TODO: Handle error.
+    }
+    defer r.Close()
+    if _, err := io.Copy(os.Stdout, r); err != nil {
+        // TODO: Handle error.
+    }
+    // Prints "This object contains text."
+
+Objects also have attributes, which you can fetch with Attrs:
+
+    objAttrs, err := obj.Attrs(ctx)
+    if err != nil {
+        // TODO: Handle error.
+    }
+    fmt.Printf("object %s has size %d and can be read using %s\n",
+        objAttrs.Name, objAttrs.Size, objAttrs.MediaLink)
+
+ACLs
+
+Both objects and buckets have ACLs (Access Control Lists). An ACL is a list of
+ACLRules, each of which specifies the role of a user, group or project. ACLs
+are suitable for fine-grained control, but you may prefer using IAM to control
+access at the project level (see
+https://cloud.google.com/storage/docs/access-control/iam).
+
+To list the ACLs of a bucket or object, obtain an ACLHandle and call its List method:
+
+    acls, err := obj.ACL().List(ctx)
+    if err != nil {
+        // TODO: Handle error.
+    }
+    for _, rule := range acls {
+        fmt.Printf("%s has role %s\n", rule.Entity, rule.Role)
+    }
+
+You can also set and delete ACLs.
+
+Conditions
+
+Every object has a generation and a metageneration. The generation changes
+whenever the content changes, and the metageneration changes whenever the
+metadata changes. Conditions let you check these values before an operation;
+the operation only executes if the conditions match. You can use conditions to
+prevent race conditions in read-modify-write operations.
+
+For example, say you've read an object's metadata into objAttrs. Now
+you want to write to that object, but only if its contents haven't changed
+since you read it. Here is how to express that:
+
+    w = obj.If(storage.Conditions{GenerationMatch: objAttrs.Generation}).NewWriter(ctx)
+    // Proceed with writing as above.
+
+Signed URLs
+
+You can obtain a URL that lets anyone read or write an object for a limited time.
+You don't need to create a client to do this. See the documentation of
+SignedURL for details.
+
+    url, err := storage.SignedURL(bucketName, "shared-object", opts)
+    if err != nil {
+        // TODO: Handle error.
+    }
+    fmt.Println(url)
+
+Authentication
+
+See examples of authorization and authentication at
+https://godoc.org/cloud.google.com/go#pkg-examples.

+### Before you contribute
+Before we can use your code, you must sign the
+[Google Individual Contributor License Agreement]
+(https://cla.developers.google.com/about/google-individual)
+(CLA), which you can do online. The CLA is necessary mainly because you own the
+copyright to your changes, even after your contribution becomes part of our
+codebase, so we need your permission to use and distribute your code. We also
+need to be sure of various other things—for instance that you'll tell us if you
+know that your code infringes on other people's patents. You don't have to sign
+the CLA until after you've submitted your code for review and a member has
+approved it, but you must do it before we can put your code into our codebase.
+Before you start working on a larger contribution, you should get in touch with
+us first through the issue tracker with your idea so that we can help out and
+possibly guide you. Coordinating up front makes it much easier to avoid
+frustration later on.
+
+### Code reviews
+All submissions, including submissions by project members, require review. We
+use Github pull requests for this purpose.

+Google API Extensions for Go
+============================
+
+[![Build Status](https://travis-ci.org/googleapis/gax-go.svg?branch=master)](https://travis-ci.org/googleapis/gax-go)
+[![Code Coverage](https://img.shields.io/codecov/c/github/googleapis/gax-go.svg)](https://codecov.io/github/googleapis/gax-go)
+
+Google API Extensions for Go (gax-go) is a set of modules which aids the
+development of APIs for clients and servers based on `gRPC` and Google API
+conventions.
+
+Application code will rarely need to use this library directly,
+but the code generated automatically from API definition files can use it
+to simplify code generation and to provide more convenient and idiomatic API surface.
+
+**This project is currently experimental and not supported.**
+
+Go Versions
+===========
+This library requires Go 1.6 or above.
+

-Want to contribute? Great! First, read this page (including the small print at the end).
-
-### Before you contribute
-Before we can use your code, you must sign the
-[Google Individual Contributor License Agreement]
-(https://cla.developers.google.com/about/google-individual)
-(CLA), which you can do online. The CLA is necessary mainly because you own the
-copyright to your changes, even after your contribution becomes part of our
-codebase, so we need your permission to use and distribute your code. We also
-need to be sure of various other things—for instance that you'll tell us if you
-know that your code infringes on other people's patents. You don't have to sign
-the CLA until after you've submitted your code for review and a member has
-approved it, but you must do it before we can put your code into our codebase.
-Before you start working on a larger contribution, you should get in touch with
-us first through the issue tracker with your idea so that we can help out and
-possibly guide you. Coordinating up front makes it much easier to avoid
-frustration later on.
-
-### Code reviews
-All submissions, including submissions by project members, require review. We
-use Github pull requests for this purpose.
-
-### The small print
-Contributions made by corporations are covered by a different agreement than
-the one above, the
-[Software Grant and Corporate Contributor License Agreement]
-(https://cla.developers.google.com/about/google-corporate).

-Google API Extensions for Go
-============================
-
-[![Build Status](https://travis-ci.org/googleapis/gax-go.svg?branch=master)](https://travis-ci.org/googleapis/gax-go)
-[![Code Coverage](https://img.shields.io/codecov/c/github/googleapis/gax-go.svg)](https://codecov.io/github/googleapis/gax-go)
-
-Google API Extensions for Go (gax-go) is a set of modules which aids the
-development of APIs for clients and servers based on `gRPC` and Google API
-conventions.
-
-Application code will rarely need to use this library directly,
-but the code generated automatically from API definition files can use it
-to simplify code generation and to provide more convenient and idiomatic API surface.
-
-**This project is currently experimental and not supported.**
-
-Go Versions
-===========
-This library requires Go 1.6 or above.
-
-License
-=======
-BSD - please see [LICENSE](https://github.com/googleapis/gax-go/blob/master/LICENSE)

+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+
+      "Contributor" shall mean Licensor and any individual or Legal Entity

+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+# OpenTracing API for Go
+
+This package is a Go platform API for OpenTracing.
+
+## Required Reading
+
+In order to understand the Go platform API, one must first be familiar with the
+[OpenTracing project](http://opentracing.io) and
+[terminology](http://opentracing.io/documentation/pages/spec.html) more specifically.
+
+## API overview for those adding instrumentation
+
+Everyday consumers of this `opentracing` package really only need to worry
+about a couple of key abstractions: the `StartSpan` function, the `Span`
+interface, and binding a `Tracer` at `main()`-time. Here are code snippets
+demonstrating some important use cases.
+
+#### Singleton initialization
+
+The simplest starting point is `./default_tracer.go`. As early as possible, call
+
+```go
+    import "github.com/opentracing/opentracing-go"
+    import ".../some_tracing_impl"
+
+    func main() {
+        opentracing.InitGlobalTracer(
+            // tracing impl specific:
+            some_tracing_impl.New(...),
+        )
+        ...
+    }
+```
+
+##### Non-Singleton initialization
+
+If you prefer direct control to singletons, manage ownership of the
+`opentracing.Tracer` implementation explicitly.
+
+#### Creating a Span given an existing Go `context.Context`
+
+If you use `context.Context` in your application, OpenTracing's Go library will
+happily rely on it for `Span` propagation. To start a new (blocking child)
+`Span`, you can use `StartSpanFromContext`.
+
+```go
+    func xyz(ctx context.Context, ...) {
+        ...
+        span, ctx := opentracing.StartSpanFromContext(ctx, "operation_name")
+        defer span.Finish()
+        span.LogFields(
+            log.String("event", "soft error"),
+            log.String("type", "cache timeout"),
+            log.Int("waited.millis", 1500))
+        ...
+    }
+```
+
+#### Starting an empty trace by creating a "root span"
+
+It's always possible to create a "root" `Span` with no parent or other causal
+reference.
+
+```go
+    func xyz() {
+        ...
+        sp := opentracing.StartSpan("operation_name")
+        defer sp.Finish()
+        ...
+    }
+```
+
+#### Creating a (child) Span given an existing (parent) Span
+
+```go
+    func xyz(parentSpan opentracing.Span, ...) {
+        ...
+        sp := opentracing.StartSpan(
+            "operation_name",
+            opentracing.ChildOf(parentSpan.Context()))
+        defer sp.Finish()
+        ...
+    }
+```
+
+#### Serializing to the wire
+
+```go
+    func makeSomeRequest(ctx context.Context) ... {
+        if span := opentracing.SpanFromContext(ctx); span != nil {
+            httpClient := &http.Client{}
+            httpReq, _ := http.NewRequest("GET", "http://myservice/", nil)
+
+            // Transmit the span's TraceContext as HTTP headers on our
+            // outbound request.
+            opentracing.GlobalTracer().Inject(
+                span.Context(),
+                opentracing.HTTPHeaders,
+                opentracing.HTTPHeadersCarrier(httpReq.Header))
+
+            resp, err := httpClient.Do(httpReq)
+            ...
+        }
+        ...
+    }
+```
+
+#### Deserializing from the wire
+
+```go
+    http.HandleFunc("/", func(w http.ResponseWriter, req *http.Request) {
+        var serverSpan opentracing.Span
+        appSpecificOperationName := ...
+        wireContext, err := opentracing.GlobalTracer().Extract(
+            opentracing.HTTPHeaders,
+            opentracing.HTTPHeadersCarrier(req.Header))
+        if err != nil {
+            // Optionally record something about err here
+        }
+
+        // Create the span referring to the RPC client if available.
+        // If wireContext == nil, a root span will be created.
+        serverSpan = opentracing.StartSpan(
+            appSpecificOperationName,
+            ext.RPCServerOption(wireContext))
+
+        defer serverSpan.Finish()
+
+        ctx := opentracing.ContextWithSpan(context.Background(), serverSpan)
+        ...
+    }
+```
+
+#### Conditionally capture a field using `log.Noop`
+
+In some situations, you may want to dynamically decide whether or not
+to log a field.  For example, you may want to capture additional data,
+such as a customer ID, in non-production environments:
+
+```go
+    func Customer(order *Order) log.Field {
+        if os.Getenv("ENVIRONMENT") == "dev" {
+            return log.String("customer", order.Customer.ID)
+        }
+        return log.Noop()
+    }
+```
+
+#### Goroutine-safety
+
+The entire public API is goroutine-safe and does not require external
+synchronization.
+
+## API pointers for those implementing a tracing system
+
+Tracing system implementors may be able to reuse or copy-paste-modify the `basictracer` package, found [here](https://github.com/opentracing/basictracer-go). In particular, see `basictracer.New(...)`.
+
+## API compatibility
+
+For the time being, "mild" backwards-incompatible changes may be made without changing the major version number. As OpenTracing and `opentracing-go` mature, backwards compatibility will become more of a priority.

+
+# Jaeger Bindings for Go OpenTracing API
+
+This is a client side library that implements an
+[OpenTracing](http://opentracing.io) Tracer,
+with Zipkin-compatible data model.
+
+## Installation
+
+We recommended using a dependency manager like [glide](https://github.com/Masterminds/glide)
+and [semantic versioning](http://semver.org/) when including this library into an application.
+For example, Jaeger backend imports this library like this:
+
+```yaml
+- package: github.com/uber/jaeger-client-go
+  version: ^2.7.0
+```
+
+If you instead want to use the latest version in `master`, you can pull it via `go get`.
+Note that during `go get` you may see build errors due to incompatible dependencies, which is why
+we recommend using semantic versions for dependencioes.  The error  may be fixed by running
+`make install` (it will install `glide` if you don't have it):
+
+```shell
+go get -u github.com/uber/jaeger-client-go/
+cd $GOPATH/src/github.com/uber/jaeger-client-go/
+git submodule update --init --recursive
+make install
+```
+
+## Initialization
+
+See tracer initialization examples in [godoc](https://godoc.org/github.com/uber/jaeger-client-go/config#pkg-examples)
+and [config/example_test.go](./config/example_test.go).
+
+### Closing the tracer via `io.Closer`
+
+The constructor functions for Jaeger Tracer return the tracer itself and an `io.Closer` instance.
+It is recommended to structure your `main()` so that it calls the `Close()` function on the closer
+before exiting, e.g.
+
+```go
+tracer, closer, err := cfg.New(...)
+defer closer.Close()
+```
+
+This is especially useful for command-line tools that enable tracing, as well as
+for the long-running apps that support graceful shutdown. For example, if your deployment
+system sends SIGTERM instead of killing the process and you trap that signal to do a graceful
+exit, then having `defer closer.Closer()` ensures that all buffered spans are flushed.
+
+### Metrics & Monitoring
+
+The tracer emits a number of different metrics, defined in
+[metrics.go](metrics.go). The monitoring backend is expected to support
+tag-based metric names, e.g. instead of `statsd`-style string names
+like `counters.my-service.jaeger.spans.started.sampled`, the metrics
+are defined by a short name and a collection of key/value tags, for
+example: `name:traces, state:started, sampled:true`.
+
+The monitoring backend is represented by the
+[StatsReporter](stats_reporter.go) interface. An implementation
+of that interface should be passed to the `New` method during
+tracer initialization:
+
+```go
+    stats := // create StatsReporter implementation
+    tracer := config.Tracing.New("your-service-name", stats)
+```
+
+By default, a no-op `NullStatsReporter` is used.
+
+### Logging
+
+The tracer can be configured with an optional logger, which will be
+used to log communication errors, or log spans if a logging reporter
+option is specified in the configuration. The logging API is abstracted
+by the [Logger](logger.go) interface. A logger instance implementing
+this interface can be set on the `Config` object before calling the
+`New` method.
+
+## Instrumentation for Tracing
+
+Since this tracer is fully compliant with OpenTracing API 1.0,
+all code instrumentation should only use the API itself, as described
+in the [opentracing-go]
+(https://github.com/opentracing/opentracing-go) documentation.
+
+## Features
+
+### Reporters
+
+A "reporter" is a component receives the finished spans and reports
+them to somewhere. Under normal circumstances, the Tracer
+should use the default `RemoteReporter`, which sends the spans out of
+process via configurable "transport". For testing purposes, one can
+use an `InMemoryReporter` that accumulates spans in a buffer and
+allows to retrieve them for later verification. Also available are
+`NullReporter`, a no-op reporter that does nothing, a `LoggingReporter`
+which logs all finished spans using their `String()` method, and a
+`CompositeReporter` that can be used to combine more than one reporter
+into one, e.g. to attach a logging reporter to the main remote reporter.
+
+### Span Reporting Transports
+
+The remote reporter uses "transports" to actually send the spans out
+of process. Currently two supported transports are Thrift over UDP
+and Thrift over TChannel. More transports will be added in the future.
+
+The only data format currently used is Zipkin Thrift 1.x span format,
+which allows easy integration of the tracer with Zipkin backend.
+
+### Sampling
+
+The tracer does not record all spans, but only those that have the
+sampling bit set in the `flags`. When a new trace is started and a new
+unique ID is generated, a sampling decision is made whether this trace
+should be sampled. The sampling decision is propagated to all downstream
+calls via the `flags` field of the trace context. The following samplers
+are available:
+  1. `RemotelyControlledSampler` uses one of the other simpler samplers
+     and periodically updates it by polling an external server. This
+     allows dynamic control of the sampling strategies.
+  1. `ConstSampler` always makes the same sampling decision for all
+     trace IDs. it can be configured to either sample all traces, or
+     to sample none.
+  1. `ProbabilisticSampler` uses a fixed sampling rate as a probability
+     for a given trace to be sampled. The actual decision is made by
+     comparing the trace ID with a random number multiplied by the
+     sampling rate.
+  1. `RateLimitingSampler` can be used to allow only a certain fixed
+     number of traces to be sampled per second.
+
+### Baggage Injection
+
+The OpenTracing spec allows for [baggage](https://github.com/opentracing/specification/blob/master/specification.md#set-a-baggage-item),
+which are key value pairs that are added to the span context and propagated
+throughout the trace.
+An external process can inject baggage by setting the special
+HTTP Header `jaeger-baggage` on a request
+
+```sh
+curl -H "jaeger-baggage: key1=value1, key2=value2" http://myhost.com
+```
+
+Baggage can also be programatically set inside your service by doing
+the following
+
+```go
+if span := opentracing.SpanFromContext(ctx); span != nil {
+    span.SetBaggageItem("key", "value")
+}
+```
+
+Another service downstream of that can retrieve the baggage in a similar way:
+
+```go
+if span := opentracing.SpanFromContext(ctx); span != nil {
+    val := span.BaggageItem("key")
+    println(val)
+}
+```
+
+### Debug Traces (Forced Sampling)
+
+#### Programmatically
+
+The OpenTracing API defines a `sampling.priority` standard tag that
+can be used to affect the sampling of a span and its children:
+
+```go
+import (
+    "github.com/opentracing/opentracing-go"
+    "github.com/opentracing/opentracing-go/ext"
+)
+
+span := opentracing.SpanFromContext(ctx)
+ext.SamplingPriority.Set(span, 1)    
+```
+
+#### Via HTTP Headers
+
+Jaeger Tracer also understands a special HTTP Header `jaeger-debug-id`,
+which can be set in the incoming request, e.g.
+
+```sh
+curl -H "jaeger-debug-id: some-correlation-id" http://myhost.com
+```
+
+When Jaeger sees this header in the request that otherwise has no
+tracing context, it ensures that the new trace started for this
+request will be sampled in the "debug" mode (meaning it should survive
+all downsampling that might happen in the collection pipeline), and the
+root span will have a tag as if this statement was executed:
+
+```go
+span.SetTag("jaeger-debug-id", "some-correlation-id")
+```
+
+This allows using Jaeger UI to find the trace by this tag.
+
+### Zipkin HTTP B3 compatible header propagation
+
+Jaeger Tracer supports Zipkin B3 Propagation HTTP headers, which are used
+by a lot of Zipkin tracers. This means that you can use Jaeger in conjunction with e.g. [these OpenZipkin tracers](https://github.com/openzipkin).
+
+However it is not the default propagation format, see [here](zipkin/README.md#NewZipkinB3HTTPHeaderPropagator) how to set it up.

+// A trace is a series of spans (often RPC calls) which form a latency tree.
+//
+// The root span is where trace_id = id and parent_id = Nil. The root span is
+// usually the longest interval in the trace, starting with a SERVER_RECV
+// annotation and ending with a SERVER_SEND.
+//
+// Attributes:
+//  - TraceID
+//  - Name: Span name in lowercase, rpc method for example
+//
+// Conventionally, when the span name isn't known, name = "unknown".
+//  - ID
+//  - ParentID
+//  - Annotations
+//  - BinaryAnnotations
+//  - Debug
+//  - Timestamp: Microseconds from epoch of the creation of this span.
+//
+// This value should be set directly by instrumentation, using the most
+// precise value possible. For example, gettimeofday or syncing nanoTime
+// against a tick of currentTimeMillis.
+//
+// For compatibilty with instrumentation that precede this field, collectors
+// or span stores can derive this via Annotation.timestamp.
+// For example, SERVER_RECV.timestamp or CLIENT_SEND.timestamp.
+//
+// This field is optional for compatibility with old data: first-party span
+// stores are expected to support this at time of introduction.
+//  - Duration: Measurement of duration in microseconds, used to support queries.
+//
+// This value should be set directly, where possible. Doing so encourages
+// precise measurement decoupled from problems of clocks, such as skew or NTP
+// updates causing time to move backwards.
+//
+// For compatibilty with instrumentation that precede this field, collectors
+// or span stores can derive this by subtracting Annotation.timestamp.
+// For example, SERVER_SEND.timestamp - SERVER_RECV.timestamp.
+//
+// If this field is persisted as unset, zipkin will continue to work, except
+// duration query support will be implementation-specific. Similarly, setting
+// this field non-atomically is implementation-specific.
+//
+// This field is i64 vs i32 to support spans longer than 35 minutes.

Subject: [PATCH 085/146] Fully fill out nulls in cloudfront data source
 (#9268)

Summary:
Previously, cloudwatch data sources would only fill in a single null value if
there was missing data. This results in behavior described in #9267. This
resolves that issue by filling the entire missing period with null values. The
null values can then be interpreted as normal by the graphing frontend.

Test Plan:
Used on a data source that had missing data for many consecutive periods.
Ensured that the graph remained at 0 across the entire window.

 ### Breaking change
 
 * **InfluxDB/Elasticsearch**: The panel & data source option named "Group by time interval" is now named "Min time interval" and does now always define a lower limit for the auto group by time. Without having to use `>` prefix (that prefix still works). This should in theory have close to zero actual impact on existing dashboards. It does mean that if you used this setting to define a hard group by time interval of, say "1d", if you zoomed to a time range wide enough the time range could increase above the "1d" range as the setting is now always considered a lower limit.
+* **Elasticsearch**: Elasticsearch metric queries without date histogram now return table formated data making table panel much easier to use for this use case. Should not break/change existing dashboards with stock panels but external panel plugins can be affected.

Subject: [PATCH 102/146] Add `DbClusterIdentifier` to CloudWatch dimensions
 (#9297)

Unfortunately CloudWatch dimensions are case-sensitive and it uses both `DBClusterIdentifier` and `DbClusterIdentifier` (notice the lower case `b`) depending on the metric. All metrics which also have the `Role` dimension appear to use `DBClusterIdentifier`, whereas metric with the `EngineName` dimension use `DbClusterIdentifier`.

- * @ngdoc type
- * @name angular.mock.TzDate
- * @description
- *
- * *NOTE*: this is not an injectable instance, just a globally available mock class of `Date`.
- *
- * Mock of the Date type which has its timezone specified via constructor arg.
- *
- * The main purpose is to create Date-like instances with timezone fixed to the specified timezone
- * offset, so that we can test code that depends on local timezone settings without dependency on
- * the time zone settings of the machine where the code is running.
- *
- * @param {number} offset Offset of the *desired* timezone in hours (fractions will be honored)
- * @param {(number|string)} timestamp Timestamp representing the desired time in *UTC*
- *
- * @example
- * !!!! WARNING !!!!!
- * This is not a complete Date object so only methods that were implemented can be called safely.
- * To make matters worse, TzDate instances inherit stuff from Date via a prototype.
- *
- * We do our best to intercept calls to "unimplemented" methods, but since the list of methods is
- * incomplete we might be missing some non-standard methods. This can result in errors like:
- * "Date.prototype.foo called on incompatible Object".
- *
- * ```js
- * var newYearInBratislava = new TzDate(-1, '2009-12-31T23:00:00Z');
- * newYearInBratislava.getTimezoneOffset() => -60;
- * newYearInBratislava.getFullYear() => 2010;

-/**
- * @ngdoc service
- * @name $httpBackend
- * @description
- * Fake HTTP backend implementation suitable for unit testing applications that use the
- * {@link ng.$http $http service}.
- *
- * <div class="alert alert-info">
- * **Note**: For fake HTTP backend implementation suitable for end-to-end testing or backend-less
- * development please see {@link ngMockE2E.$httpBackend e2e $httpBackend mock}.
- * </div>
- *
- * During unit testing, we want our unit tests to run quickly and have no external dependencies so
- * we don’t want to send [XHR](https://developer.mozilla.org/en/xmlhttprequest) or
- * [JSONP](http://en.wikipedia.org/wiki/JSONP) requests to a real server. All we really need is
- * to verify whether a certain request has been sent or not, or alternatively just let the
- * application make requests, respond with pre-trained responses and assert that the end result is
- * what we expect it to be.
- *
- * This mock implementation can be used to respond with static or dynamic responses via the
- * `expect` and `when` apis and their shortcuts (`expectGET`, `whenPOST`, etc).
- *
- * When an Angular application needs some data from a server, it calls the $http service, which
- * sends the request to a real server using $httpBackend service. With dependency injection, it is
- * easy to inject $httpBackend mock (which has the same API as $httpBackend) and use it to verify
- * the requests and respond with some testing data without sending a request to a real server.
- *
- * There are two ways to specify what test data should be returned as http responses by the mock
- * backend when the code under test makes http requests:
- *
- * - `$httpBackend.expect` - specifies a request expectation
- * - `$httpBackend.when` - specifies a backend definition
- *
- *
- * ## Request Expectations vs Backend Definitions
- *
- * Request expectations provide a way to make assertions about requests made by the application and
- * to define responses for those requests. The test will fail if the expected requests are not made
- * or they are made in the wrong order.
- *
- * Backend definitions allow you to define a fake backend for your application which doesn't assert
- * if a particular request was made or not, it just returns a trained response if a request is made.
- * The test will pass whether or not the request gets made during testing.
- *
- *
- * <table class="table">
- *   <tr><th width="220px"></th><th>Request expectations</th><th>Backend definitions</th></tr>
- *   <tr>
- *     <th>Syntax</th>
- *     <td>.expect(...).respond(...)</td>
- *     <td>.when(...).respond(...)</td>
- *   </tr>
- *   <tr>
- *     <th>Typical usage</th>
- *     <td>strict unit tests</td>
- *     <td>loose (black-box) unit testing</td>
- *   </tr>
- *   <tr>
- *     <th>Fulfills multiple requests</th>
- *     <td>NO</td>
- *     <td>YES</td>
- *   </tr>
- *   <tr>
- *     <th>Order of requests matters</th>
- *     <td>YES</td>
- *     <td>NO</td>
- *   </tr>
- *   <tr>
- *     <th>Request required</th>
- *     <td>YES</td>
- *     <td>NO</td>
- *   </tr>
- *   <tr>
- *     <th>Response required</th>
- *     <td>optional (see below)</td>
- *     <td>YES</td>
- *   </tr>
- * </table>
- *
- * In cases where both backend definitions and request expectations are specified during unit
- * testing, the request expectations are evaluated first.
- *
- * If a request expectation has no response specified, the algorithm will search your backend
- * definitions for an appropriate response.
- *
- * If a request didn't match any expectation or if the expectation doesn't have the response
- * defined, the backend definitions are evaluated in sequential order to see if any of them match
- * the request. The response from the first matched definition is returned.
- *
- *
- * ## Flushing HTTP requests
- *
- * The $httpBackend used in production always responds to requests asynchronously. If we preserved
- * this behavior in unit testing, we'd have to create async unit tests, which are hard to write,
- * to follow and to maintain. But neither can the testing mock respond synchronously; that would
- * change the execution of the code under test. For this reason, the mock $httpBackend has a
- * `flush()` method, which allows the test to explicitly flush pending requests. This preserves
- * the async api of the backend, while allowing the test to execute synchronously.
- *
- *
- * ## Unit testing with mock $httpBackend
- * The following code shows how to setup and use the mock backend when unit testing a controller.
- * First we create the controller under test:
- *
-  ```js
-  // The module code
-  angular
-    .module('MyApp', [])
-    .controller('MyController', MyController);
-
-  // The controller code
-  function MyController($scope, $http) {
-    var authToken;
-
-    $http.get('/auth.py').then(function(response) {
-      authToken = response.headers('A-Token');
-      $scope.user = response.data;
-    });
-
-    $scope.saveMessage = function(message) {
-      var headers = { 'Authorization': authToken };
-      $scope.status = 'Saving...';
-
-      $http.post('/add-msg.py', message, { headers: headers } ).then(function(response) {
-        $scope.status = '';
-      }).catch(function() {
-        $scope.status = 'Failed...';
-      });
-    };
-  }

-       var $httpBackend, $rootScope, createController, authRequestHandler;

-         $rootScope = $injector.get('$rootScope');
-         // The $controller service is used to create instances of controllers
-         var $controller = $injector.get('$controller');
-
-         createController = function() {
-           return $controller('MyController', {'$scope' : $rootScope });

-         $httpBackend.verifyNoOutstandingExpectation();
-         $httpBackend.verifyNoOutstandingRequest();

-
-
-       it('should fetch authentication token', function() {
-         $httpBackend.expectGET('/auth.py');
-         var controller = createController();

-
-         // now you don’t care about the authentication, but
-         // the controller will still send the request and
-         // $httpBackend will respond without you having to
-         // specify the expectation and response for this request
-
-         $httpBackend.expectPOST('/add-msg.py', 'message content').respond(201, '');
-         $rootScope.saveMessage('message content');
-         expect($rootScope.status).toBe('Saving...');
-         $httpBackend.flush();
-         expect($rootScope.status).toBe('');
-       });

-
-       it('should send auth header', function() {

-         }).respond(201, '');
-
-         $rootScope.saveMessage('whatever');
-         $httpBackend.flush();
-       });
-    });
-  ```
- *
- * ## Dynamic responses
- *
- * You define a response to a request by chaining a call to `respond()` onto a definition or expectation.
- * If you provide a **callback** as the first parameter to `respond(callback)` then you can dynamically generate
- * a response based on the properties of the request.
- *
- * The `callback` function should be of the form `function(method, url, data, headers, params)`.
- *
- * ### Query parameters
- *
- * By default, query parameters on request URLs are parsed into the `params` object. So a request URL
- * of `/list?q=searchstr&orderby=-name` would set `params` to be `{q: 'searchstr', orderby: '-name'}`.
- *
- * ### Regex parameter matching
- *
- * If an expectation or definition uses a **regex** to match the URL, you can provide an array of **keys** via a
- * `params` argument. The index of each **key** in the array will match the index of a **group** in the
- * **regex**.
- *
- * The `params` object in the **callback** will now have properties with these keys, which hold the value of the
- * corresponding **group** in the **regex**.
- *
- * This also applies to the `when` and `expect` shortcut methods.
- *
- *
- * ```js
- *   $httpBackend.expect('GET', /\/user\/(.+)/, undefined, undefined, ['id'])
- *     .respond(function(method, url, data, headers, params) {
- *       // for requested url of '/user/1234' params is {id: '1234'}
- *     });
- *
- *   $httpBackend.whenPATCH(/\/user\/(.+)\/article\/(.+)/, undefined, undefined, ['user', 'article'])
- *     .respond(function(method, url, data, headers, params) {
- *       // for url of '/user/1234/article/567' params is {user: '1234', article: '567'}
- *     });
- * ```
- *
- * ## Matching route requests
- *
- * For extra convenience, `whenRoute` and `expectRoute` shortcuts are available. These methods offer colon
- * delimited matching of the url path, ignoring the query string. This allows declarations
- * similar to how application routes are configured with `$routeProvider`. Because these methods convert
- * the definition url to regex, declaration order is important. Combined with query parameter parsing,
- * the following is possible:
- *
-  ```js
-    $httpBackend.whenRoute('GET', '/users/:id')
-      .respond(function(method, url, data, headers, params) {
-        return [200, MockUserList[Number(params.id)]];
-      });
-
-    $httpBackend.whenRoute('GET', '/users')
-      .respond(function(method, url, data, headers, params) {
-        var userList = angular.copy(MockUserList),
-          defaultSort = 'lastName',
-          count, pages, isPrevious, isNext;
-
-        // paged api response '/v1/users?page=2'
-        params.page = Number(params.page) || 1;
-
-        // query for last names '/v1/users?q=Archer'
-        if (params.q) {
-          userList = $filter('filter')({lastName: params.q});
-        }
-
-        pages = Math.ceil(userList.length / pagingLength);
-        isPrevious = params.page > 1;
-        isNext = params.page < pages;
-
-        return [200, {
-          count:    userList.length,
-          previous: isPrevious,
-          next:     isNext,
-          // sort field -> '/v1/users?sortBy=firstName'
-          results:  $filter('orderBy')(userList, params.sortBy || defaultSort)
-                      .splice((params.page - 1) * pagingLength, pagingLength)
-        }];
-      });
-  ```

- * @name $controller
- * @description
- * A decorator for {@link ng.$controller} with additional `bindings` parameter, useful when testing
- * controllers of directives that use {@link $compile#-bindtocontroller- `bindToController`}.
- *
- * Depending on the value of
- * {@link ng.$compileProvider#preAssignBindingsEnabled `preAssignBindingsEnabled()`}, the properties
- * will be bound before or after invoking the constructor.
- *
- *
- * ## Example
- *
- * ```js
- *
- * // Directive definition ...
- *
- * myMod.directive('myDirective', {
- *   controller: 'MyDirectiveController',
- *   bindToController: {
- *     name: '@'
- *   }
- * });
- *
- *
- * // Controller definition ...
- *
- * myMod.controller('MyDirectiveController', ['$log', function($log) {
- *   this.log = function() {
- *     $log.info(this.name);
- *   };
- * }]);
- *
- *
- * // In a test ...
- *
- * describe('myDirectiveController', function() {
- *   describe('log()', function() {
- *     it('should write the bound name to the log', inject(function($controller, $log) {
- *       var ctrl = $controller('MyDirectiveController', { /* no locals &#42;/ }, { name: 'Clark Kent' });
- *       ctrl.log();
- *
- *       expect(ctrl.name).toEqual('Clark Kent');
- *       expect($log.info.logs).toEqual(['Clark Kent']);
- *     }));
- *   });
- * });
- *
- * ```
- *
- * @param {Function|string} constructor If called with a function then it's considered to be the
- *    controller constructor function. Otherwise it's considered to be a string which is used
- *    to retrieve the controller constructor using the following steps:
- *
- *    * check if a controller with given name is registered via `$controllerProvider`
- *    * check if evaluating the string on the current scope returns a constructor
- *    * if $controllerProvider#allowGlobals, check `window[constructor]` on the global
- *      `window` object (deprecated, not recommended)
- *
- *    The string can use the `controller as property` syntax, where the controller instance is published
- *    as the specified property on the `scope`; the `scope` must be injected into `locals` param for this
- *    to work correctly.
- *
- * @param {Object} locals Injection locals for Controller.
- * @param {Object=} bindings Properties to add to the controller instance. This is used to simulate
- *                           the `bindToController` feature and simplify certain kinds of tests.

- * @description
- *
- * # ngMock
- *
- * The `ngMock` module provides support to inject and mock Angular services into unit tests.
- * In addition, ngMock also extends various core ng services such that they can be
- * inspected and controlled in a synchronous manner within test code.
- *
- *
- * <div doc-module-components="ngMock"></div>
- *
- * @installation
- *
- *  First, download the file:
- *  * [Google CDN](https://developers.google.com/speed/libraries/devguide#angularjs) e.g.
- *    `"//ajax.googleapis.com/ajax/libs/angularjs/X.Y.Z/angular-mocks.js"`
- *  * [NPM](https://www.npmjs.com/) e.g. `npm install angular-mocks@X.Y.Z`
- *  * [Yarn](https://yarnpkg.com) e.g. `yarn add angular-mocks@X.Y.Z`
- *  * [Bower](http://bower.io) e.g. `bower install angular-mocks#X.Y.Z`
- *  * [code.angularjs.org](https://code.angularjs.org/) (discouraged for production use)  e.g.
- *    `"//code.angularjs.org/X.Y.Z/angular-mocks.js"`
- *
- * where X.Y.Z is the AngularJS version you are running.
- *
- * Then, configure your test runner to load `angular-mocks.js` after `angular.js`.
- * This example uses <a href="http://karma-runner.github.io/">Karma</a>:
- *
- * ```
- * config.set({
- *   files: [
- *     'build/angular.js', // and other module files you need
- *     'build/angular-mocks.js',
- *     '<path/to/application/files>',
- *     '<path/to/spec/files>'
- *   ]
- * });
- * ```
- *
- * Including the `angular-mocks.js` file automatically adds the `ngMock` module, so your tests
- *  are ready to go!

-/**
- * @ngdoc service
- * @name $httpBackend
- * @module ngMockE2E
- * @description
- * Fake HTTP backend implementation suitable for end-to-end testing or backend-less development of
- * applications that use the {@link ng.$http $http service}.
- *
- * <div class="alert alert-info">
- * **Note**: For fake http backend implementation suitable for unit testing please see
- * {@link ngMock.$httpBackend unit-testing $httpBackend mock}.
- * </div>
- *
- * This implementation can be used to respond with static or dynamic responses via the `when` api
- * and its shortcuts (`whenGET`, `whenPOST`, etc) and optionally pass through requests to the
- * real $httpBackend for specific requests (e.g. to interact with certain remote apis or to fetch
- * templates from a webserver).
- *
- * As opposed to unit-testing, in an end-to-end testing scenario or in scenario when an application
- * is being developed with the real backend api replaced with a mock, it is often desirable for
- * certain category of requests to bypass the mock and issue a real http request (e.g. to fetch
- * templates or static files from the webserver). To configure the backend with this behavior
- * use the `passThrough` request handler of `when` instead of `respond`.
- *
- * Additionally, we don't want to manually have to flush mocked out requests like we do during unit
- * testing. For this reason the e2e $httpBackend flushes mocked out requests
- * automatically, closely simulating the behavior of the XMLHttpRequest object.
- *
- * To setup the application to run with this http backend, you have to create a module that depends
- * on the `ngMockE2E` and your application modules and defines the fake backend:
- *
- * ```js
- *   var myAppDev = angular.module('myAppDev', ['myApp', 'ngMockE2E']);
- *   myAppDev.run(function($httpBackend) {
- *     var phones = [{name: 'phone1'}, {name: 'phone2'}];
- *
- *     // returns the current list of phones
- *     $httpBackend.whenGET('/phones').respond(phones);
- *
- *     // adds a new phone to the phones array
- *     $httpBackend.whenPOST('/phones').respond(function(method, url, data) {
- *       var phone = angular.fromJson(data);
- *       phones.push(phone);
- *       return [200, phone, {}];
- *     });
- *     $httpBackend.whenGET(/^\/templates\//).passThrough(); // Requests for templates are handled by the real server
- *     //...
- *   });
- * ```
- *
- * Afterwards, bootstrap your app with this new module.
- *
- * ## Example
- * <example name="httpbackend-e2e-testing" module="myAppE2E" deps="angular-mocks.js">
- * <file name="app.js">
- *   var myApp = angular.module('myApp', []);

- *     ctrl.addPhone = function(phone) {
- *       $http.post('/phones', phone).then(function() {
- *         ctrl.newPhone = {name: ''};
- *         return ctrl.getPhones();

-   * This contrasts with the default behaviour where a new injector is created per test case.
-   *
-   * Use sharedInjector when you want to take advantage of Jasmine's `beforeAll()`, or mocha's
-   * `before()` methods. Call `module.sharedInjector()` before you setup any other hooks that
-   * will create (i.e call `module()`) or use (i.e call `inject()`) the injector.
-   *
-   * You cannot call `sharedInjector()` from within a context already using `sharedInjector()`.
-   *
-   * ## Example
-   *
-   * Typically beforeAll is used to make many assertions about a single operation. This can
-   * cut down test run-time as the test setup doesn't need to be re-run, and enabling focussed
-   * tests each with a single assertion.
-   *
-   * ```js
-   * describe("Deep Thought", function() {
-   *
-   *   module.sharedInjector();
-   *
-   *   beforeAll(module("UltimateQuestion"));
-   *
-   *   beforeAll(inject(function(DeepThought) {
-   *     expect(DeepThought.answer).toBeUndefined();
-   *     DeepThought.generateAnswer();
-   *   }));
-   *
-   *   it("has calculated the answer correctly", inject(function(DeepThought) {
-   *     // Because of sharedInjector, we have access to the instance of the DeepThought service
-   *     // that was provided to the beforeAll() hook. Therefore we can test the generated answer
-   *     expect(DeepThought.answer).toBe(42);
-   *   }));
-   *
-   *   it("has calculated the answer within the expected time", inject(function(DeepThought) {
-   *     expect(DeepThought.runTimeMillennia).toBeLessThan(8000);
-   *   }));
-   *
-   *   it("has double checked the answer", inject(function(DeepThought) {
-   *     expect(DeepThought.absolutelySureItIsTheRightAnswer).toBe(true);
-   *   }));
-   *
-   * });

-   * @ngdoc function
-   * @name angular.mock.inject
-   * @description
-   *
-   * *NOTE*: This function is also published on window for easy access.<br>
-   * *NOTE*: This function is declared ONLY WHEN running tests with jasmine or mocha
-   *
-   * The inject function wraps a function into an injectable function. The inject() creates new
-   * instance of {@link auto.$injector $injector} per test, which is then used for
-   * resolving references.
-   *
-   *
-   * ## Resolving References (Underscore Wrapping)
-   * Often, we would like to inject a reference once, in a `beforeEach()` block and reuse this
-   * in multiple `it()` clauses. To be able to do this we must assign the reference to a variable
-   * that is declared in the scope of the `describe()` block. Since we would, most likely, want
-   * the variable to have the same name of the reference we have a problem, since the parameter
-   * to the `inject()` function would hide the outer variable.
-   *
-   * To help with this, the injected parameters can, optionally, be enclosed with underscores.
-   * These are ignored by the injector when the reference name is resolved.
-   *
-   * For example, the parameter `_myService_` would be resolved as the reference `myService`.
-   * Since it is available in the function body as `_myService_`, we can then assign it to a variable
-   * defined in an outer scope.
-   *
-   * ```
-   * // Defined out reference variable outside
-   * var myService;
-   *
-   * // Wrap the parameter in underscores
-   * beforeEach( inject( function(_myService_){
-   *   myService = _myService_;
-   * }));
-   *
-   * // Use myService in a series of tests.
-   * it('makes use of myService', function() {
-   *   myService.doStuff();
-   * });
-   *
-   * ```
-   *
-   * See also {@link angular.mock.module angular.mock.module}
-   *
-   * ## Example
-   * Example of what a typical jasmine tests looks like with the inject method.
-   * ```js
-   *
-   *   angular.module('myApplicationModule', [])
-   *       .value('mode', 'app')
-   *       .value('version', 'v1.0.1');
-   *
-   *
-   *   describe('MyApp', function() {
-   *
-   *     // You need to load modules that you want to test,
-   *     // it loads only the "ng" module by default.
-   *     beforeEach(module('myApplicationModule'));
-   *
-   *
-   *     // inject() is used to inject arguments of all given functions
-   *     it('should provide a version', inject(function(mode, version) {
-   *       expect(version).toEqual('v1.0.1');
-   *       expect(mode).toEqual('app');
-   *     }));
-   *
-   *
-   *     // The inject and module method can also be used inside of the it or beforeEach
-   *     it('should override a version and test the new version is injected', function() {
-   *       // module() takes functions or strings (module aliases)
-   *       module(function($provide) {
-   *         $provide.value('version', 'overridden'); // override version here
-   *       });
-   *
-   *       inject(function(version) {
-   *         expect(version).toEqual('overridden');
-   *       });
-   *     });
-   *   });
-   *
-   * ```
-   *
-   * @param {...Function} fns any number of functions which will be injected using the injector.

-   * @param {string} path Route path (matched against `$location.path`). If `$location.path`
-   *    contains redundant trailing slash or is missing one, the route will still match and the
-   *    `$location.path` will be updated to add or drop the trailing slash to exactly match the
-   *    route definition.
-   *
-   *    * `path` can contain named groups starting with a colon: e.g. `:name`. All characters up
-   *        to the next slash are matched and stored in `$routeParams` under the given `name`
-   *        when the route matches.
-   *    * `path` can contain named groups starting with a colon and ending with a star:
-   *        e.g.`:name*`. All characters are eagerly stored in `$routeParams` under the given `name`
-   *        when the route matches.
-   *    * `path` can contain optional named groups with a question mark: e.g.`:name?`.
-   *
-   *    For example, routes like `/color/:color/largecode/:largecode*\/edit` will match
-   *    `/color/brown/largecode/code/with/slashes/edit` and extract:
-   *
-   *    * `color: brown`
-   *    * `largecode: code/with/slashes`.
-   *
-   *
-   * @param {Object} route Mapping information to be assigned to `$route.current` on route
-   *    match.
-   *
-   *    Object properties:
-   *
-   *    - `controller` – `{(string|Function)=}` – Controller fn that should be associated with
-   *      newly created scope or the name of a {@link angular.Module#controller registered
-   *      controller} if passed as a string.
-   *    - `controllerAs` – `{string=}` – An identifier name for a reference to the controller.
-   *      If present, the controller will be published to scope under the `controllerAs` name.
-   *    - `template` – `{(string|Function)=}` – html template as a string or a function that
-   *      returns an html template as a string which should be used by {@link
-   *      ngRoute.directive:ngView ngView} or {@link ng.directive:ngInclude ngInclude} directives.
-   *      This property takes precedence over `templateUrl`.
-   *
-   *      If `template` is a function, it will be called with the following parameters:
-   *
-   *      - `{Array.<Object>}` - route parameters extracted from the current
-   *        `$location.path()` by applying the current route
-   *
-   *      One of `template` or `templateUrl` is required.
-   *
-   *    - `templateUrl` – `{(string|Function)=}` – path or function that returns a path to an html
-   *      template that should be used by {@link ngRoute.directive:ngView ngView}.
-   *
-   *      If `templateUrl` is a function, it will be called with the following parameters:
-   *
-   *      - `{Array.<Object>}` - route parameters extracted from the current
-   *        `$location.path()` by applying the current route
-   *
-   *      One of `templateUrl` or `template` is required.
-   *
-   *    - `resolve` - `{Object.<string, Function>=}` - An optional map of dependencies which should
-   *      be injected into the controller. If any of these dependencies are promises, the router
-   *      will wait for them all to be resolved or one to be rejected before the controller is
-   *      instantiated.
-   *      If all the promises are resolved successfully, the values of the resolved promises are
-   *      injected and {@link ngRoute.$route#$routeChangeSuccess $routeChangeSuccess} event is
-   *      fired. If any of the promises are rejected the
-   *      {@link ngRoute.$route#$routeChangeError $routeChangeError} event is fired.
-   *      For easier access to the resolved dependencies from the template, the `resolve` map will
-   *      be available on the scope of the route, under `$resolve` (by default) or a custom name
-   *      specified by the `resolveAs` property (see below). This can be particularly useful, when
-   *      working with {@link angular.Module#component components} as route templates.<br />
-   *      <div class="alert alert-warning">
-   *        **Note:** If your scope already contains a property with this name, it will be hidden
-   *        or overwritten. Make sure, you specify an appropriate name for this property, that
-   *        does not collide with other properties on the scope.
-   *      </div>
-   *      The map object is:
-   *
-   *      - `key` – `{string}`: a name of a dependency to be injected into the controller.
-   *      - `factory` - `{string|Function}`: If `string` then it is an alias for a service.
-   *        Otherwise if function, then it is {@link auto.$injector#invoke injected}
-   *        and the return value is treated as the dependency. If the result is a promise, it is
-   *        resolved before its value is injected into the controller. Be aware that
-   *        `ngRoute.$routeParams` will still refer to the previous route within these resolve
-   *        functions.  Use `$route.current.params` to access the new route parameters, instead.
-   *
-   *    - `resolveAs` - `{string=}` - The name under which the `resolve` map will be available on
-   *      the scope of the route. If omitted, defaults to `$resolve`.
-   *
-   *    - `redirectTo` – `{(string|Function)=}` – value to update
-   *      {@link ng.$location $location} path with and trigger route redirection.
-   *
-   *      If `redirectTo` is a function, it will be called with the following parameters:
-   *
-   *      - `{Object.<string>}` - route parameters extracted from the current
-   *        `$location.path()` by applying the current route templateUrl.
-   *      - `{string}` - current `$location.path()`
-   *      - `{Object}` - current `$location.search()`
-   *
-   *      The custom `redirectTo` function is expected to return a string which will be used
-   *      to update `$location.url()`. If the function throws an error, no further processing will
-   *      take place and the {@link ngRoute.$route#$routeChangeError $routeChangeError} event will
-   *      be fired.
-   *
-   *      Routes that specify `redirectTo` will not have their controllers, template functions
-   *      or resolves called, the `$location` will be changed to the redirect url and route
-   *      processing will stop. The exception to this is if the `redirectTo` is a function that
-   *      returns `undefined`. In this case the route transition occurs as though there was no
-   *      redirection.
-   *
-   *    - `resolveRedirectTo` – `{Function=}` – a function that will (eventually) return the value
-   *      to update {@link ng.$location $location} URL with and trigger route redirection. In
-   *      contrast to `redirectTo`, dependencies can be injected into `resolveRedirectTo` and the
-   *      return value can be either a string or a promise that will be resolved to a string.
-   *
-   *      Similar to `redirectTo`, if the return value is `undefined` (or a promise that gets
-   *      resolved to `undefined`), no redirection takes place and the route transition occurs as
-   *      though there was no redirection.
-   *
-   *      If the function throws an error or the returned promise gets rejected, no further
-   *      processing will take place and the
-   *      {@link ngRoute.$route#$routeChangeError $routeChangeError} event will be fired.
-   *
-   *      `redirectTo` takes precedence over `resolveRedirectTo`, so specifying both on the same
-   *      route definition, will cause the latter to be ignored.
-   *
-   *    - `[reloadOnSearch=true]` - `{boolean=}` - reload route when only `$location.search()`
-   *      or `$location.hash()` changes.
-   *
-   *      If the option is set to `false` and url in the browser changes, then
-   *      `$routeUpdate` event is broadcasted on the root scope.
-   *
-   *    - `[caseInsensitiveMatch=false]` - `{boolean=}` - match routes without being case sensitive
-   *
-   *      If the option is set to `true`, then the particular route can be matched without being
-   *      case sensitive
-   *
-   * @returns {Object} self

-     *   - `locals`: A map of locals which is used by {@link ng.$controller $controller} service for
-     *     controller instantiation. The `locals` contain
-     *     the resolved values of the `resolve` map. Additionally the `locals` also contain:
-     *
-     *     - `$scope` - The current route scope.
-     *     - `$template` - The current route template HTML.
-     *
-     *     The `locals` will be assigned to the route scope's `$resolve` property. You can override
-     *     the property name, using `resolveAs` in the route definition. See
-     *     {@link ngRoute.$routeProvider $routeProvider} for more info.
-     *
-     * @property {Object} routes Object with all route configuration Objects as its properties.
-     *
-     * @description
-     * `$route` is used for deep-linking URLs to controllers and views (HTML partials).
-     * It watches `$location.url()` and tries to map the path to an existing route definition.
-     *
-     * Requires the {@link ngRoute `ngRoute`} module to be installed.
-     *
-     * You can define routes through {@link ngRoute.$routeProvider $routeProvider}'s API.
-     *
-     * The `$route` service is typically used in conjunction with the
-     * {@link ngRoute.directive:ngView `ngView`} directive and the
-     * {@link ngRoute.$routeParams `$routeParams`} service.
-     *
-     * @example
-     * This example shows how changing the URL hash causes the `$route` to match a route against the
-     * URL, and the `ngView` pulls in the partial.

- * @ngdoc service
- * @name $routeParams
- * @requires $route
- * @this
- *
- * @description
- * The `$routeParams` service allows you to retrieve the current set of route parameters.
- *
- * Requires the {@link ngRoute `ngRoute`} module to be installed.
- *
- * The route parameters are a combination of {@link ng.$location `$location`}'s
- * {@link ng.$location#search `search()`} and {@link ng.$location#path `path()`}.
- * The `path` parameters are extracted when the {@link ngRoute.$route `$route`} path is matched.
- *
- * In case of parameter name collision, `path` params take precedence over `search` params.
- *
- * The service guarantees that the identity of the `$routeParams` object will remain unchanged
- * (but its properties will likely change) even when a route change occurs.
- *
- * Note that the `$routeParams` are only updated *after* a route change completes successfully.
- * This means that you cannot rely on `$routeParams` being correct in route resolve functions.
- * Instead you can use `$route.current.params` to access the new route's parameters.
- *
- * @example
- * ```js
- *  // Given:
- *  // URL: http://server.com/index.html#/Chapter/1/Section/2?search=moby
- *  // Route: /Chapter/:chapterId/Section/:sectionId
- *  //
- *  // Then
- *  $routeParams ==> {chapterId:'1', sectionId:'2', search:'moby'}
- * ```

-/**
- * @ngdoc directive
- * @name ngView
- * @restrict ECA
- *
- * @description
- * # Overview
- * `ngView` is a directive that complements the {@link ngRoute.$route $route} service by
- * including the rendered template of the current route into the main layout (`index.html`) file.
- * Every time the current route changes, the included view changes with it according to the
- * configuration of the `$route` service.
- *
- * Requires the {@link ngRoute `ngRoute`} module to be installed.
- *
- * @animations
- * | Animation                        | Occurs                              |
- * |----------------------------------|-------------------------------------|
- * | {@link ng.$animate#enter enter}  | when the new element is inserted to the DOM |
- * | {@link ng.$animate#leave leave}  | when the old element is removed from to the DOM  |
- *
- * The enter and leave animation occur concurrently.
- *
- * @scope
- * @priority 400
- * @param {string=} onload Expression to evaluate whenever the view updates.
- *
- * @param {string=} autoscroll Whether `ngView` should call {@link ng.$anchorScroll
- *                  $anchorScroll} to scroll the viewport after the view is updated.
- *
- *                  - If the attribute is not set, disable scrolling.
- *                  - If the attribute is set without value, enable scrolling.
- *                  - Otherwise enable scrolling only if the `autoscroll` attribute value evaluated
- *                    as an expression yields a truthy value.

- * @ngdoc service
- * @name $sanitize
- * @kind function
- *
- * @description
- *   Sanitizes an html string by stripping all potentially dangerous tokens.
- *
- *   The input is sanitized by parsing the HTML into tokens. All safe tokens (from a whitelist) are
- *   then serialized back to properly escaped html string. This means that no unsafe input can make
- *   it into the returned string.
- *
- *   The whitelist for URL sanitization of attribute values is configured using the functions
- *   `aHrefSanitizationWhitelist` and `imgSrcSanitizationWhitelist` of {@link ng.$compileProvider
- *   `$compileProvider`}.
- *
- *   The input may also contain SVG markup if this is enabled via {@link $sanitizeProvider}.
- *
- * @param {string} html HTML input.
- * @returns {string} Sanitized HTML.

- * @ngdoc filter
- * @name linky
- * @kind function
- *
- * @description
- * Finds links in text input and turns them into html links. Supports `http/https/ftp/mailto` and
- * plain email address links.
- *
- * Requires the {@link ngSanitize `ngSanitize`} module to be installed.
- *
- * @param {string} text Input text.
- * @param {string} target Window (`_blank|_self|_parent|_top`) or named frame to open links in.
- * @param {object|function(url)} [attributes] Add custom attributes to the link element.
- *
- *    Can be one of:
- *
- *    - `object`: A map of attributes
- *    - `function`: Takes the url as a parameter and returns a map of attributes
- *
- *    If the map of attributes contains a value for `target`, it overrides the value of
- *    the target parameter.

- * @description
- *
- * This object provides a utility for producing rich Error messages within
- * Angular. It can be called as follows:
- *
- * var exampleMinErr = minErr('example');
- * throw exampleMinErr('one', 'This {0} is {1}', foo, bar);
- *
- * The above creates an instance of minErr in the example namespace. The
- * resulting error will have a namespaced error code of example.one.  The
- * resulting error will replace {0} with the value of foo, and {1} with the
- * value of bar. The object is not restricted in the number of arguments it can
- * take.
- *
- * If fewer arguments are specified than necessary for interpolation, the extra
- * interpolation markers will be preserved in the final string.
- *
- * Since data will be parsed statically during a build step, some restrictions
- * are applied with respect to how minErr instances are created and called.
- * Instances should have names of the form namespaceMinErr for a minErr created
- * using minErr('namespace') . Error codes, namespaces and template strings
- * should all be static strings, not variables or general expressions.
- *
- * @param {string} module The namespace to use for the new minErr instance.
- * @param {function} ErrorConstructor Custom error constructor to be instantiated when returning
- *   error from returned function, for cases when a particular type of error is useful.
- * @returns {function(code:string, template:string, ...templateArgs): Error} minErr instance

- * return the value provided.

- * @ngdoc function
- * @name angular.equals
- * @module ng
- * @kind function
- *
- * @description
- * Determines if two objects or two values are equivalent. Supports value types, regular
- * expressions, arrays and objects.
- *
- * Two objects or values are considered equivalent if at least one of the following is true:
- *
- * * Both objects or values pass `===` comparison.
- * * Both objects or values are of the same type and all of their properties are equal by
- *   comparing them with `angular.equals`.
- * * Both values are NaN. (In JavaScript, NaN == NaN => false. But we consider two NaN as equal)
- * * Both values represent the same regular expression (In JavaScript,
- *   /abc/ == /abc/ => false. But we consider two regular expressions as equal when their textual
- *   representation matches).
- *
- * During a property comparison, properties of `function` type and properties with names
- * that begin with `$` are ignored.
- *
- * Scope and DOMWindow objects are being compared only by identify (`===`).
- *
- * @param {*} o1 Object or value to compare.
- * @param {*} o2 Object or value to compare.
- * @returns {boolean} True if arguments are equal.

- * @description
- *
- * Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
- * designates the **root element** of the application and is typically placed near the root element
- * of the page - e.g. on the `<body>` or `<html>` tags.
- *
- * There are a few things to keep in mind when using `ngApp`:
- * - only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
- *   found in the document will be used to define the root element to auto-bootstrap as an
- *   application. To run multiple applications in an HTML document you must manually bootstrap them using
- *   {@link angular.bootstrap} instead.
- * - AngularJS applications cannot be nested within each other.
- * - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`.
- *   This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and
- *   {@link ngRoute.ngView `ngView`}.
- *   Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},
- *   causing animations to stop working and making the injector inaccessible from outside the app.
- *
- * You can specify an **AngularJS module** to be used as the root module for the application.  This
- * module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It
- * should contain the application code needed or have dependencies on other modules that will
- * contain the code. See {@link angular.module} for more information.
- *
- * In the example below if the `ngApp` directive were not placed on the `html` element then the
- * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
- * would not be resolved to `3`.
- *
- * `ngApp` is the easiest, and most common way to bootstrap an application.
- *
- <example module="ngAppDemo" name="ng-app">
-   <file name="index.html">
-   <div ng-controller="ngAppDemoController">
-     I can add: {{a}} + {{b}} =  {{ a+b }}
-   </div>
-   </file>
-   <file name="script.js">
-   angular.module('ngAppDemo', []).controller('ngAppDemoController', function($scope) {
-     $scope.a = 1;
-     $scope.b = 2;
-   });
-   </file>
- </example>
- *
- * Using `ngStrictDi`, you would see something like this:
- *
- <example ng-app-included="true" name="strict-di">
-   <file name="index.html">
-   <div ng-app="ngAppStrictDemo" ng-strict-di>
-       <div ng-controller="GoodController1">
-           I can add: {{a}} + {{b}} =  {{ a+b }}
-
-           <p>This renders because the controller does not fail to
-              instantiate, by using explicit annotation style (see
-              script.js for details)
-           </p>
-       </div>
-
-       <div ng-controller="GoodController2">
-           Name: <input ng-model="name"><br />
-           Hello, {{name}}!
-
-           <p>This renders because the controller does not fail to
-              instantiate, by using explicit annotation style
-              (see script.js for details)
-           </p>

-           I can add: {{a}} + {{b}} =  {{ a+b }}

-     * The `angular.module` is a global place for creating, registering and retrieving Angular
-     * modules.
-     * All modules (angular core or 3rd party) that should be available to an application must be
-     * registered using this mechanism.

-     *
-     *
-     * # Module
-     *
-     * A module is a collection of services, directives, controllers, filters, and configuration information.
-     * `angular.module` is used to configure the {@link auto.$injector $injector}.
-     *
-     * ```js
-     * // Create a new module
-     * var myModule = angular.module('myModule', []);
-     *
-     * // register a new service
-     * myModule.value('appName', 'MyCoolApp');
-     *
-     * // configure existing services inside initialization blocks.
-     * myModule.config(['$locationProvider', function($locationProvider) {
-     *   // Configure existing providers
-     *   $locationProvider.hashPrefix('!');
-     * }]);
-     * ```
-     *
-     * Then you can create an injector and load your modules like this:
-     *
-     * ```js
-     * var injector = angular.injector(['ng', 'myModule'])
-     * ```
-     *
-     * However it's more likely that you'll just use

-     * {@link angular.bootstrap} to simplify this process for you.

-/**
- * @ngdoc function
- * @name angular.element
- * @module ng
- * @kind function
- *
- * @description
- * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
- *
- * If jQuery is available, `angular.element` is an alias for the
- * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
- * delegates to Angular's built-in subset of jQuery, called "jQuery lite" or **jqLite**.
- *
- * jqLite is a tiny, API-compatible subset of jQuery that allows
- * Angular to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most
- * commonly needed functionality with the goal of having a very small footprint.
- *
- * To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the
- * {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a
- * specific version of jQuery if multiple versions exist on the page.
- *
- * <div class="alert alert-info">**Note:** All element references in Angular are always wrapped with jQuery or
- * jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.</div>
- *
- * <div class="alert alert-warning">**Note:** Keep in mind that this function will not find elements
- * by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)`
- * or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.</div>
- *
- * ## Angular's jqLite
- * jqLite provides only the following jQuery methods:
- *
- * - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument
- * - [`after()`](http://api.jquery.com/after/)
- * - [`append()`](http://api.jquery.com/append/)
- * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters
- * - [`bind()`](http://api.jquery.com/bind/) (_deprecated_, use [`on()`](http://api.jquery.com/on/)) - Does not support namespaces, selectors or eventData
- * - [`children()`](http://api.jquery.com/children/) - Does not support selectors
- * - [`clone()`](http://api.jquery.com/clone/)
- * - [`contents()`](http://api.jquery.com/contents/)
- * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`.
- *   As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.
- * - [`data()`](http://api.jquery.com/data/)
- * - [`detach()`](http://api.jquery.com/detach/)
- * - [`empty()`](http://api.jquery.com/empty/)
- * - [`eq()`](http://api.jquery.com/eq/)
- * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
- * - [`hasClass()`](http://api.jquery.com/hasClass/)
- * - [`html()`](http://api.jquery.com/html/)
- * - [`next()`](http://api.jquery.com/next/) - Does not support selectors
- * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
- * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter
- * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
- * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
- * - [`prepend()`](http://api.jquery.com/prepend/)
- * - [`prop()`](http://api.jquery.com/prop/)
- * - [`ready()`](http://api.jquery.com/ready/) (_deprecated_, use `angular.element(callback)` instead of `angular.element(document).ready(callback)`)
- * - [`remove()`](http://api.jquery.com/remove/)
- * - [`removeAttr()`](http://api.jquery.com/removeAttr/) - Does not support multiple attributes
- * - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument
- * - [`removeData()`](http://api.jquery.com/removeData/)
- * - [`replaceWith()`](http://api.jquery.com/replaceWith/)
- * - [`text()`](http://api.jquery.com/text/)
- * - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument
- * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers
- * - [`unbind()`](http://api.jquery.com/unbind/) (_deprecated_, use [`off()`](http://api.jquery.com/off/)) - Does not support namespaces or event object as parameter
- * - [`val()`](http://api.jquery.com/val/)
- * - [`wrap()`](http://api.jquery.com/wrap/)
- *
- * ## jQuery/jqLite Extras
- * Angular also provides the following additional methods and events to both jQuery and jqLite:
- *
- * ### Events
- * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
- *    on all DOM nodes being removed.  This can be used to clean up any 3rd party bindings to the DOM
- *    element before it is removed.
- *
- * ### Methods
- * - `controller(name)` - retrieves the controller of the current element or its parent. By default
- *   retrieves controller associated with the `ngController` directive. If `name` is provided as
- *   camelCase directive name, then the controller for this directive will be retrieved (e.g.
- *   `'ngModel'`).
- * - `injector()` - retrieves the injector of the current element or its parent.
- * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current
- *   element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to
- *   be enabled.
- * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the
- *   current element. This getter should be used only on elements that contain a directive which starts a new isolate
- *   scope. Calling `scope()` on this element always returns the original non-isolate scope.
- *   Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.
- * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
- *   parent element is reached.
- *
- * @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See
- * https://github.com/angular/angular.js/issues/14251 for more information.
- *
- * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
- * @returns {Object} jQuery object.

- * @ngdoc function
- * @module ng
- * @name angular.injector
- * @kind function
- *
- * @description
- * Creates an injector object that can be used for retrieving services as well as for
- * dependency injection (see {@link guide/di dependency injection}).
- *
- * @param {Array.<string|Function>} modules A list of module functions or their aliases. See
- *     {@link angular.module}. The `ng` module must be explicitly added.
- * @param {boolean=} [strictDi=false] Whether the injector should be in strict mode, which
- *     disallows argument name annotation inference.
- * @returns {injector} Injector object. See {@link auto.$injector $injector}.
- *
- * @example
- * Typical usage
- * ```js
- *   // create an injector
- *   var $injector = angular.injector(['ng']);
- *
- *   // use the injector to kick off your application
- *   // use the type inference to auto inject arguments, or use implicit injection
- *   $injector.invoke(function($rootScope, $compile, $document) {
- *     $compile($document)($rootScope);
- *     $rootScope.$digest();
- *   });
- * ```
- *
- * Sometimes you want to get access to the injector of a currently running Angular app
- * from outside Angular. Perhaps, you want to inject and compile some markup after the
- * application has been bootstrapped. You can do this using the extra `injector()` added
- * to JQuery/jqLite elements. See {@link angular.element}.
- *
- * *This is fairly rare but could be the case if a third party library is injecting the
- * markup.*
- *
- * In the following example a new block of HTML containing a `ng-controller`
- * directive is added to the end of the document body by JQuery. We then compile and link
- * it into the current AngularJS scope.
- *
- * ```js
- * var $div = $('<div ng-controller="MyCtrl">{{content.label}}</div>');
- * $(document.body).append($div);
- *
- * angular.element(document).injector().invoke(function($compile) {
- *   var scope = angular.element($div).scope();
- *   $compile($div)(scope);
- * });
- * ```

-/**
- * @ngdoc service
- * @name $injector
- *
- * @description
- *
- * `$injector` is used to retrieve object instances as defined by
- * {@link auto.$provide provider}, instantiate types, invoke methods,
- * and load modules.
- *
- * The following always holds true:
- *
- * ```js
- *   var $injector = angular.injector();
- *   expect($injector.get('$injector')).toBe($injector);
- *   expect($injector.invoke(function($injector) {
- *     return $injector;
- *   })).toBe($injector);
- * ```
- *
- * # Injection Function Annotation
- *
- * JavaScript does not have annotations, and annotations are needed for dependency injection. The
- * following are all valid ways of annotating function with injection arguments and are equivalent.
- *
- * ```js
- *   // inferred (only works if code not minified/obfuscated)
- *   $injector.invoke(function(serviceA){});
- *
- *   // annotated
- *   function explicit(serviceA) {};
- *   explicit.$inject = ['serviceA'];
- *   $injector.invoke(explicit);
- *
- *   // inline
- *   $injector.invoke(['serviceA', function(serviceA){}]);
- * ```
- *
- * ## Inference
- *
- * In JavaScript calling `toString()` on a function returns the function definition. The definition
- * can then be parsed and the function arguments can be extracted. This method of discovering
- * annotations is disallowed when the injector is in strict mode.
- * *NOTE:* This does not work with minification, and obfuscation tools since these tools change the
- * argument names.
- *
- * ## `$inject` Annotation
- * By adding an `$inject` property onto a function the injection parameters can be specified.
- *
- * ## Inline
- * As an array of injection names, where the last item in the array is the function to call.

-/**
- * @ngdoc method
- * @name $injector#annotate
- *
- * @description
- * Returns an array of service names which the function is requesting for injection. This API is
- * used by the injector to determine which services need to be injected into the function when the
- * function is invoked. There are three ways in which the function can be annotated with the needed
- * dependencies.
- *
- * # Argument names
- *
- * The simplest form is to extract the dependencies from the arguments of the function. This is done
- * by converting the function into a string using `toString()` method and extracting the argument
- * names.
- * ```js
- *   // Given
- *   function MyController($scope, $route) {
- *     // ...
- *   }
- *
- *   // Then
- *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
- * ```
- *
- * You can disallow this method by using strict injection mode.
- *
- * This method does not work with code minification / obfuscation. For this reason the following
- * annotation strategies are supported.
- *
- * # The `$inject` property
- *
- * If a function has an `$inject` property and its value is an array of strings, then the strings
- * represent names of services to be injected into the function.
- * ```js
- *   // Given
- *   var MyController = function(obfuscatedScope, obfuscatedRoute) {
- *     // ...
- *   }
- *   // Define function dependencies
- *   MyController['$inject'] = ['$scope', '$route'];
- *
- *   // Then
- *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
- * ```
- *
- * # The array notation
- *
- * It is often desirable to inline Injected functions and that's when setting the `$inject` property
- * is very inconvenient. In these situations using the array notation to specify the dependencies in
- * a way that survives minification is a better choice:
- *
- * ```js
- *   // We wish to write this (not minification / obfuscation safe)
- *   injector.invoke(function($compile, $rootScope) {
- *     // ...
- *   });
- *
- *   // We are forced to write break inlining
- *   var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
- *     // ...
- *   };
- *   tmpFn.$inject = ['$compile', '$rootScope'];
- *   injector.invoke(tmpFn);
- *
- *   // To better support inline function the inline annotation is supported
- *   injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
- *     // ...
- *   }]);
- *
- *   // Therefore
- *   expect(injector.annotate(
- *      ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
- *    ).toEqual(['$compile', '$rootScope']);
- * ```
- *
- * @param {Function|Array.<string|Function>} fn Function for which dependent service names need to
- * be retrieved as described above.
- *
- * @param {boolean=} [strictDi=false] Disallow argument name annotation inference.
- *
- * @returns {Array.<string>} The names of the services which the function requires.

-/**
- * @ngdoc service
- * @name $provide
- *
- * @description
- *
- * The {@link auto.$provide $provide} service has a number of methods for registering components
- * with the {@link auto.$injector $injector}. Many of these functions are also exposed on
- * {@link angular.Module}.
- *
- * An Angular **service** is a singleton object created by a **service factory**.  These **service
- * factories** are functions which, in turn, are created by a **service provider**.
- * The **service providers** are constructor functions. When instantiated they must contain a
- * property called `$get`, which holds the **service factory** function.
- *
- * When you request a service, the {@link auto.$injector $injector} is responsible for finding the
- * correct **service provider**, instantiating it and then calling its `$get` **service factory**
- * function to get the instance of the **service**.
- *
- * Often services have no configuration options and there is no need to add methods to the service
- * provider.  The provider will be no more than a constructor function with a `$get` property. For
- * these cases the {@link auto.$provide $provide} service has additional helper methods to register
- * services without specifying a provider.
- *
- * * {@link auto.$provide#provider provider(name, provider)} - registers a **service provider** with the
- *     {@link auto.$injector $injector}
- * * {@link auto.$provide#constant constant(name, obj)} - registers a value/object that can be accessed by
- *     providers and services.
- * * {@link auto.$provide#value value(name, obj)} - registers a value/object that can only be accessed by
- *     services, not providers.
- * * {@link auto.$provide#factory factory(name, fn)} - registers a service **factory function**
- *     that will be wrapped in a **service provider** object, whose `$get` property will contain the
- *     given factory function.
- * * {@link auto.$provide#service service(name, Fn)} - registers a **constructor function**
- *     that will be wrapped in a **service provider** object, whose `$get` property will instantiate
- *      a new object using the given constructor function.
- * * {@link auto.$provide#decorator decorator(name, decorFn)} - registers a **decorator function** that
- *      will be able to modify or replace the implementation of another service.
- *
- * See the individual methods for more information and examples.

-/**
- * @ngdoc method
- * @name $provide#provider
- * @description
- *
- * Register a **provider function** with the {@link auto.$injector $injector}. Provider functions
- * are constructor functions, whose instances are responsible for "providing" a factory for a
- * service.
- *
- * Service provider names start with the name of the service they provide followed by `Provider`.
- * For example, the {@link ng.$log $log} service has a provider called
- * {@link ng.$logProvider $logProvider}.
- *
- * Service provider objects can have additional methods which allow configuration of the provider
- * and its service. Importantly, you can configure what kind of service is created by the `$get`
- * method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
- * method {@link ng.$logProvider#debugEnabled debugEnabled}
- * which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
- * console or not.
- *
- * @param {string} name The name of the instance. NOTE: the provider will be available under `name +
-                        'Provider'` key.
- * @param {(Object|function())} provider If the provider is:
- *
- *   - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
- *     {@link auto.$injector#invoke $injector.invoke()} when an instance needs to be created.
- *   - `Constructor`: a new instance of the provider will be created using
- *     {@link auto.$injector#instantiate $injector.instantiate()}, then treated as `object`.
- *
- * @returns {Object} registered provider instance
-
- * @example
- *
- * The following example shows how to create a simple event tracking service and register it using
- * {@link auto.$provide#provider $provide.provider()}.
- *
- * ```js
- *  // Define the eventTracker provider
- *  function EventTrackerProvider() {
- *    var trackingUrl = '/track';

-   * @description
-   * When called, it scrolls to the element related to the specified `hash` or (if omitted) to the
-   * current value of {@link ng.$location#hash $location.hash()}, according to the rules specified

-   * [HTML5 spec](http://www.w3.org/html/wg/drafts/html/master/browsers.html#an-indicated-part-of-the-document).
-   *
-   * It also watches the {@link ng.$location#hash $location.hash()} and automatically scrolls to
-   * match any anchor whenever it changes. This can be disabled by calling
-   * {@link ng.$anchorScrollProvider#disableAutoScrolling $anchorScrollProvider.disableAutoScrolling()}.
-   *
-   * Additionally, you can use its {@link ng.$anchorScroll#yOffset yOffset} property to specify a
-   * vertical scroll-offset (either fixed or dynamic).
-   *
-   * @param {string=} hash The hash specifying the element to scroll to. If omitted, the value of
-   *                       {@link ng.$location#hash $location.hash()} will be used.
-   *
-   * @property {(number|function|jqLite)} yOffset
-   * If set, specifies a vertical scroll-offset. This is often useful when there are fixed
-   * positioned elements at the top of the page, such as navbars, headers etc.
-   *
-   * `yOffset` can be specified in various ways:
-   * - **number**: A fixed number of pixels to be used as offset.<br /><br />
-   * - **function**: A getter function called everytime `$anchorScroll()` is executed. Must return
-   *   a number representing the offset (in pixels).<br /><br />
-   * - **jqLite**: A jqLite/jQuery element to be used for specifying the offset. The distance from
-   *   the top of the page to the element's bottom will be used as offset.<br />
-   *   **Note**: The element will be taken into account only as long as its `position` is set to
-   *   `fixed`. This option is useful, when dealing with responsive navbars/headers that adjust
-   *   their height and/or positioning according to the viewport's size.
-   *
-   * <br />
-   * <div class="alert alert-warning">
-   * In order for `yOffset` to work properly, scrolling should take place on the document's root and
-   * not some child element.

- * @name $compile
- * @kind function
- *
- * @description
- * Compiles an HTML string or DOM into a template and produces a template function, which
- * can then be used to link {@link ng.$rootScope.Scope `scope`} and the template together.
- *
- * The compilation is a process of walking the DOM tree and matching DOM elements to
- * {@link ng.$compileProvider#directive directives}.
- *
- * <div class="alert alert-warning">
- * **Note:** This document is an in-depth reference of all directive options.
- * For a gentle introduction to directives with examples of common use cases,
- * see the {@link guide/directive directive guide}.
- * </div>
- *
- * ## Comprehensive Directive API
- *
- * There are many different options for a directive.
- *
- * The difference resides in the return value of the factory function.
- * You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)}
- * that defines the directive properties, or just the `postLink` function (all other properties will have
- * the default values).
- *
- * <div class="alert alert-success">
- * **Best Practice:** It's recommended to use the "directive definition object" form.
- * </div>
- *
- * Here's an example directive declared with a Directive Definition Object:
- *
- * ```js
- *   var myModule = angular.module(...);
- *
- *   myModule.directive('directiveName', function factory(injectables) {
- *     var directiveDefinitionObject = {
- *       {@link $compile#-priority- priority}: 0,
- *       {@link $compile#-template- template}: '<div></div>', // or // function(tElement, tAttrs) { ... },
- *       // or
- *       // {@link $compile#-templateurl- templateUrl}: 'directive.html', // or // function(tElement, tAttrs) { ... },
- *       {@link $compile#-transclude- transclude}: false,
- *       {@link $compile#-restrict- restrict}: 'A',
- *       {@link $compile#-templatenamespace- templateNamespace}: 'html',
- *       {@link $compile#-scope- scope}: false,
- *       {@link $compile#-controller- controller}: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
- *       {@link $compile#-controlleras- controllerAs}: 'stringIdentifier',
- *       {@link $compile#-bindtocontroller- bindToController}: false,
- *       {@link $compile#-require- require}: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
- *       {@link $compile#-multielement- multiElement}: false,
- *       {@link $compile#-compile- compile}: function compile(tElement, tAttrs, transclude) {
- *         return {
- *            {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },
- *            {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
- *         }
- *         // or
- *         // return function postLink( ... ) { ... }
- *       },
- *       // or
- *       // {@link $compile#-link- link}: {
- *       //  {@link $compile#pre-linking-function pre}: function preLink(scope, iElement, iAttrs, controller) { ... },
- *       //  {@link $compile#post-linking-function post}: function postLink(scope, iElement, iAttrs, controller) { ... }
- *       // }
- *       // or
- *       // {@link $compile#-link- link}: function postLink( ... ) { ... }
- *     };
- *     return directiveDefinitionObject;
- *   });
- * ```
- *
- * <div class="alert alert-warning">
- * **Note:** Any unspecified options will use the default value. You can see the default values below.
- * </div>
- *
- * Therefore the above can be simplified as:
- *
- * ```js
- *   var myModule = angular.module(...);
- *
- *   myModule.directive('directiveName', function factory(injectables) {
- *     var directiveDefinitionObject = {
- *       link: function postLink(scope, iElement, iAttrs) { ... }
- *     };
- *     return directiveDefinitionObject;
- *     // or
- *     // return function postLink(scope, iElement, iAttrs) { ... }
- *   });
- * ```
- *
- * ### Life-cycle hooks
- * Directive controllers can provide the following methods that are called by Angular at points in the life-cycle of the
- * directive:
- * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and
- *   had their bindings initialized (and before the pre &amp; post linking functions for the directives on
- *   this element). This is a good place to put initialization code for your controller.
- * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The
- *   `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an
- *   object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a
- *   component such as cloning the bound value to prevent accidental mutation of the outer value.
- * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on
- *   changes. Any actions that you wish to take in response to the changes that you detect must be
- *   invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook
- *   could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not
- *   be detected by Angular's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments;
- *   if detecting changes, you must store the previous value(s) for comparison to the current values.
- * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing
- *   external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in
- *   the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent
- *   components will have their `$onDestroy()` hook called before child components.
- * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link
- *   function this hook can be used to set up DOM event handlers and do direct DOM manipulation.
- *   Note that child elements that contain `templateUrl` directives will not have been compiled and linked since
- *   they are waiting for their template to load asynchronously and their own compilation and linking has been
- *   suspended until that occurs.
- *
- * #### Comparison with Angular 2 life-cycle hooks
- * Angular 2 also uses life-cycle hooks for its components. While the Angular 1 life-cycle hooks are similar there are
- * some differences that you should be aware of, especially when it comes to moving your code from Angular 1 to Angular 2:
- *
- * * Angular 1 hooks are prefixed with `$`, such as `$onInit`. Angular 2 hooks are prefixed with `ng`, such as `ngOnInit`.
- * * Angular 1 hooks can be defined on the controller prototype or added to the controller inside its constructor.
- *   In Angular 2 you can only define hooks on the prototype of the Component class.
- * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in Angular 1 than you would to
- *   `ngDoCheck` in Angular 2
- * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be
- *   propagated throughout the application.
- *   Angular 2 does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an
- *   error or do nothing depending upon the state of `enableProdMode()`.
- *
- * #### Life-cycle hook examples
- *
- * This example shows how you can check for mutations to a Date object even though the identity of the object
- * has not changed.
- *
- * <example name="doCheckDateExample" module="do-check-module">
- *   <file name="app.js">
- *     angular.module('do-check-module', [])
- *       .component('app', {
- *         template:
- *           'Month: <input ng-model="$ctrl.month" ng-change="$ctrl.updateDate()">' +
- *           'Date: {{ $ctrl.date }}' +
- *           '<test date="$ctrl.date"></test>',
- *         controller: function() {
- *           this.date = new Date();
- *           this.month = this.date.getMonth();
- *           this.updateDate = function() {
- *             this.date.setMonth(this.month);
- *           };
- *         }
- *       })
- *       .component('test', {
- *         bindings: { date: '<' },
- *         template:
- *           '<pre>{{ $ctrl.log | json }}</pre>',
- *         controller: function() {
- *           var previousValue;
- *           this.log = [];
- *           this.$doCheck = function() {
- *             var currentValue = this.date && this.date.valueOf();
- *             if (previousValue !== currentValue) {
- *               this.log.push('doCheck: date mutated: ' + this.date);
- *               previousValue = currentValue;
- *             }
- *           };
- *         }
- *       });
- *   </file>
- *   <file name="index.html">
- *     <app></app>
- *   </file>
- * </example>
- *
- * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the
- * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large
- * arrays or objects can have a negative impact on your application performance)
- *
- * <example name="doCheckArrayExample" module="do-check-module">
- *   <file name="index.html">
- *     <div ng-init="items = []">
- *       <button ng-click="items.push(items.length)">Add Item</button>
- *       <button ng-click="items = []">Reset Items</button>
- *       <pre>{{ items }}</pre>
- *       <test items="items"></test>
- *     </div>
- *   </file>
- *   <file name="app.js">
- *      angular.module('do-check-module', [])
- *        .component('test', {
- *          bindings: { items: '<' },
- *          template:
- *            '<pre>{{ $ctrl.log | json }}</pre>',
- *          controller: function() {
- *            this.log = [];
- *
- *            this.$doCheck = function() {
- *              if (this.items_ref !== this.items) {
- *                this.log.push('doCheck: items changed');
- *                this.items_ref = this.items;
- *              }
- *              if (!angular.equals(this.items_clone, this.items)) {
- *                this.log.push('doCheck: items mutated');
- *                this.items_clone = angular.copy(this.items);
- *              }
- *            };
- *          }
- *        });
- *   </file>
- * </example>

- * ### Directive Definition Object
- *
- * The directive definition object provides instructions to the {@link ng.$compile
- * compiler}. The attributes are:
- *
- * #### `multiElement`
- * When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between
- * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
- * together as the directive elements. It is recommended that this feature be used on directives
- * which are not strictly behavioral (such as {@link ngClick}), and which
- * do not manipulate or replace child nodes (such as {@link ngInclude}).
- *
- * #### `priority`
- * When there are multiple directives defined on a single DOM element, sometimes it
- * is necessary to specify the order in which the directives are applied. The `priority` is used
- * to sort the directives before their `compile` functions get called. Priority is defined as a
- * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
- * are also run in priority order, but post-link functions are run in reverse order. The order
- * of directives with the same priority is undefined. The default priority is `0`.
- *
- * #### `terminal`
- * If set to true then the current `priority` will be the last set of directives
- * which will execute (any directives at the current priority will still execute
- * as the order of execution on same `priority` is undefined). Note that expressions
- * and other directives used in the directive's template will also be excluded from execution.
- *
- * #### `scope`
- * The scope property can be `false`, `true`, or an object:
- *
- * * **`false` (default):** No scope will be created for the directive. The directive will use its
- * parent's scope.
- *
- * * **`true`:** A new child scope that prototypically inherits from its parent will be created for
- * the directive's element. If multiple directives on the same element request a new scope,
- * only one new scope is created.
- *
- * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's element. The
- * 'isolate' scope differs from normal scope in that it does not prototypically inherit from its parent
- * scope. This is useful when creating reusable components, which should not accidentally read or modify
- * data in the parent scope.
- *
- * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the
- * directive's element. These local properties are useful for aliasing values for templates. The keys in
- * the object hash map to the name of the property on the isolate scope; the values define how the property
- * is bound to the parent scope, via matching attributes on the directive's element:
- *
- * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
- *   always a string since DOM attributes are strings. If no `attr` name is specified then the
- *   attribute name is assumed to be the same as the local name. Given `<my-component
- *   my-attr="hello {{name}}">` and the isolate scope definition `scope: { localName:'@myAttr' }`,
- *   the directive's scope property `localName` will reflect the interpolated value of `hello
- *   {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's
- *   scope. The `name` is read from the parent scope (not the directive's scope).
- *
- * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression
- *   passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.
- *   If no `attr` name is specified then the attribute name is assumed to be the same as the local
- *   name. Given `<my-component my-attr="parentModel">` and the isolate scope definition `scope: {
- *   localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the
- *   value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in
- *   `localModel` and vice versa. Optional attributes should be marked as such with a question mark:
- *   `=?` or `=?attr`. If the binding expression is non-assignable, or if the attribute isn't
- *   optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`})
- *   will be thrown upon discovering changes to the local value, since it will be impossible to sync
- *   them back to the parent scope. By default, the {@link ng.$rootScope.Scope#$watch `$watch`}
- *   method is used for tracking changes, and the equality check is based on object identity.
- *   However, if an object literal or an array literal is passed as the binding expression, the
- *   equality check is done by value (using the {@link angular.equals} function). It's also possible
- *   to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection
- *   `$watchCollection`}: use `=*` or `=*attr` (`=*?` or `=*?attr` if the attribute is optional).
- *
-  * * `<` or `<attr` - set up a one-way (one-directional) binding between a local scope property and an
- *   expression passed via the attribute `attr`. The expression is evaluated in the context of the
- *   parent scope. If no `attr` name is specified then the attribute name is assumed to be the same as the
- *   local name. You can also make the binding optional by adding `?`: `<?` or `<?attr`.
- *
- *   For example, given `<my-component my-attr="parentModel">` and directive definition of
- *   `scope: { localModel:'<myAttr' }`, then the isolated scope property `localModel` will reflect the
- *   value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected
- *   in `localModel`, but changes in `localModel` will not reflect in `parentModel`. There are however
- *   two caveats:
- *     1. one-way binding does not copy the value from the parent to the isolate scope, it simply
- *     sets the same value. That means if your bound value is an object, changes to its properties
- *     in the isolated scope will be reflected in the parent scope (because both reference the same object).
- *     2. one-way binding watches changes to the **identity** of the parent value. That means the
- *     {@link ng.$rootScope.Scope#$watch `$watch`} on the parent value only fires if the reference
- *     to the value has changed. In most cases, this should not be of concern, but can be important
- *     to know if you one-way bind to an object, and then replace that object in the isolated scope.
- *     If you now change a property of the object in your parent scope, the change will not be
- *     propagated to the isolated scope, because the identity of the object on the parent scope
- *     has not changed. Instead you must assign a new object.
- *
- *   One-way binding is useful if you do not plan to propagate changes to your isolated scope bindings
- *   back to the parent. However, it does not make this completely impossible.
- *
- * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope. If
- *   no `attr` name is specified then the attribute name is assumed to be the same as the local name.
- *   Given `<my-component my-attr="count = count + value">` and the isolate scope definition `scope: {
- *   localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for
- *   the `count = count + value` expression. Often it's desirable to pass data from the isolated scope
- *   via an expression to the parent scope. This can be done by passing a map of local variable names
- *   and values into the expression wrapper fn. For example, if the expression is `increment(amount)`
- *   then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.
- *
- * In general it's possible to apply more than one directive to one element, but there might be limitations
- * depending on the type of scope required by the directives. The following points will help explain these limitations.
- * For simplicity only two directives are taken into account, but it is also applicable for several directives:
- *
- * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope
- * * **child scope** + **no scope** =>  Both directives will share one single child scope
- * * **child scope** + **child scope** =>  Both directives will share one single child scope
- * * **isolated scope** + **no scope** =>  The isolated directive will use it's own created isolated scope. The other directive will use
- * its parent's scope
- * * **isolated scope** + **child scope** =>  **Won't work!** Only one scope can be related to one element. Therefore these directives cannot
- * be applied to the same element.
- * * **isolated scope** + **isolated scope**  =>  **Won't work!** Only one scope can be related to one element. Therefore these directives
- * cannot be applied to the same element.
- *
- *
- * #### `bindToController`
- * This property is used to bind scope properties directly to the controller. It can be either
- * `true` or an object hash with the same format as the `scope` property.
- *
- * When an isolate scope is used for a directive (see above), `bindToController: true` will
- * allow a component to have its properties bound to the controller, rather than to scope.
- *
- * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller
- * properties. You can access these bindings once they have been initialized by providing a controller method called
- * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings
- * initialized.
- *
- * <div class="alert alert-warning">
- * **Deprecation warning:** although bindings for non-ES6 class controllers are currently
- * bound to `this` before the controller constructor is called, this use is now deprecated. Please place initialization
- * code that relies upon bindings inside a `$onInit` method on the controller, instead.
- * </div>
- *
- * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.
- * This will set up the scope bindings to the controller directly. Note that `scope` can still be used
- * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate
- * scope (useful for component directives).
- *
- * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.
- *
- *
- * #### `controller`
- * Controller constructor function. The controller is instantiated before the
- * pre-linking phase and can be accessed by other directives (see
- * `require` attribute). This allows the directives to communicate with each other and augment
- * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
- *
- * * `$scope` - Current scope associated with the element
- * * `$element` - Current element
- * * `$attrs` - Current attributes object for the element
- * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
- *   `function([scope], cloneLinkingFn, futureParentElement, slotName)`:
- *    * `scope`: (optional) override the scope.
- *    * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.
- *    * `futureParentElement` (optional):
- *        * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
- *        * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
- *        * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
- *          and when the `cloneLinkingFn` is passed,
- *          as those elements need to created and cloned in a special way when they are defined outside their
- *          usual containers (e.g. like `<svg>`).
- *        * See also the `directive.templateNamespace` property.
- *    * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`)
- *      then the default transclusion is provided.
- *    The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns
- *    `true` if the specified slot contains content (i.e. one or more DOM nodes).
- *
- * #### `require`
- * Require another directive and inject its controller as the fourth argument to the linking function. The
- * `require` property can be a string, an array or an object:
- * * a **string** containing the name of the directive to pass to the linking function
- * * an **array** containing the names of directives to pass to the linking function. The argument passed to the
- * linking function will be an array of controllers in the same order as the names in the `require` property
- * * an **object** whose property values are the names of the directives to pass to the linking function. The argument
- * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding
- * controllers.
- *
- * If the `require` property is an object and `bindToController` is truthy, then the required controllers are
- * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers
- * have been constructed but before `$onInit` is called.
- * If the name of the required controller is the same as the local name (the key), the name can be
- * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`.
- * See the {@link $compileProvider#component} helper for an example of how this can be used.
- * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is
- * raised (unless no link function is specified and the required controllers are not being bound to the directive
- * controller, in which case error checking is skipped). The name can be prefixed with:
- *
- * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
- * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
- * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
- * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.
- * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
- *   `null` to the `link` fn if not found.
- * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass
- *   `null` to the `link` fn if not found.
- *
- *
- * #### `controllerAs`
- * Identifier name for a reference to the controller in the directive's scope.
- * This allows the controller to be referenced from the directive template. This is especially
- * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible
- * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the
- * `controllerAs` reference might overwrite a property that already exists on the parent scope.
- *
- *
- * #### `restrict`
- * String of subset of `EACM` which restricts the directive to a specific directive
- * declaration style. If omitted, the defaults (elements and attributes) are used.
- *
- * * `E` - Element name (default): `<my-directive></my-directive>`
- * * `A` - Attribute (default): `<div my-directive="exp"></div>`
- * * `C` - Class: `<div class="my-directive: exp;"></div>`
- * * `M` - Comment: `<!-- directive: my-directive exp -->`
- *
- *
- * #### `templateNamespace`
- * String representing the document type used by the markup in the template.
- * AngularJS needs this information as those elements need to be created and cloned
- * in a special way when they are defined outside their usual containers like `<svg>` and `<math>`.
- *
- * * `html` - All root nodes in the template are HTML. Root nodes may also be
- *   top-level elements such as `<svg>` or `<math>`.
- * * `svg` - The root nodes in the template are SVG elements (excluding `<math>`).
- * * `math` - The root nodes in the template are MathML elements (excluding `<svg>`).
- *
- * If no `templateNamespace` is specified, then the namespace is considered to be `html`.
- *
- * #### `template`
- * HTML markup that may:
- * * Replace the contents of the directive's element (default).
- * * Replace the directive's element itself (if `replace` is true - DEPRECATED).
- * * Wrap the contents of the directive's element (if `transclude` is true).
- *
- * Value may be:
- *
- * * A string. For example `<div red-on-hover>{{delete_str}}</div>`.
- * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
- *   function api below) and returns a string value.
- *
- *
- * #### `templateUrl`
- * This is similar to `template` but the template is loaded from the specified URL, asynchronously.
- *
- * Because template loading is asynchronous the compiler will suspend compilation of directives on that element
- * for later when the template has been resolved.  In the meantime it will continue to compile and link
- * sibling and parent elements as though this element had not contained any directives.
- *
- * The compiler does not suspend the entire compilation to wait for templates to be loaded because this
- * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
- * case when only one deeply nested directive has `templateUrl`.
- *
- * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
- *
- * You can specify `templateUrl` as a string representing the URL or as a function which takes two
- * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
- * a string value representing the url.  In either case, the template URL is passed through {@link
- * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
- *
- *
- * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0)
- * specify what the template should replace. Defaults to `false`.
- *
- * * `true` - the template will replace the directive's element.
- * * `false` - the template will replace the contents of the directive's element.
- *
- * The replacement process migrates all of the attributes / classes from the old element to the new
- * one. See the {@link guide/directive#template-expanding-directive
- * Directives Guide} for an example.
- *
- * There are very few scenarios where element replacement is required for the application function,
- * the main one being reusable custom components that are used within SVG contexts
- * (because SVG doesn't work with custom elements in the DOM tree).
- *
- * #### `transclude`
- * Extract the contents of the element where the directive appears and make it available to the directive.
- * The contents are compiled and provided to the directive as a **transclusion function**. See the
- * {@link $compile#transclusion Transclusion} section below.
- *
- *
- * #### `compile`
- *
- * ```js
- *   function compile(tElement, tAttrs, transclude) { ... }
- * ```
- *
- * The compile function deals with transforming the template DOM. Since most directives do not do
- * template transformation, it is not used often. The compile function takes the following arguments:
- *
- *   * `tElement` - template element - The element where the directive has been declared. It is
- *     safe to do template transformation on the element and child elements only.
- *
- *   * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
- *     between all directive compile functions.
- *
- *   * `transclude` -  [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
- *
- * <div class="alert alert-warning">
- * **Note:** The template instance and the link instance may be different objects if the template has
- * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
- * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
- * should be done in a linking function rather than in a compile function.
- * </div>
-
- * <div class="alert alert-warning">
- * **Note:** The compile function cannot handle directives that recursively use themselves in their
- * own templates or compile functions. Compiling these directives results in an infinite loop and
- * stack overflow errors.
- *
- * This can be avoided by manually using $compile in the postLink function to imperatively compile
- * a directive's template instead of relying on automatic template compilation via `template` or
- * `templateUrl` declaration or manual compilation inside the compile function.
- * </div>
- *
- * <div class="alert alert-danger">
- * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
- *   e.g. does not know about the right outer scope. Please use the transclude function that is passed
- *   to the link function instead.
- * </div>
-
- * A compile function can have a return value which can be either a function or an object.
- *
- * * returning a (post-link) function - is equivalent to registering the linking function via the
- *   `link` property of the config object when the compile function is empty.
- *
- * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
- *   control when a linking function should be called during the linking phase. See info about
- *   pre-linking and post-linking functions below.
- *
- *
- * #### `link`
- * This property is used only if the `compile` property is not defined.
- *
- * ```js
- *   function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
- * ```
- *
- * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
- * executed after the template has been cloned. This is where most of the directive logic will be
- * put.
- *
- *   * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
- *     directive for registering {@link ng.$rootScope.Scope#$watch watches}.
- *
- *   * `iElement` - instance element - The element where the directive is to be used. It is safe to
- *     manipulate the children of the element only in `postLink` function since the children have
- *     already been linked.
- *
- *   * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
- *     between all directive linking functions.
- *
- *   * `controller` - the directive's required controller instance(s) - Instances are shared
- *     among all directives, which allows the directives to use the controllers as a communication
- *     channel. The exact value depends on the directive's `require` property:
- *       * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one
- *       * `string`: the controller instance
- *       * `array`: array of controller instances
- *
- *     If a required controller cannot be found, and it is optional, the instance is `null`,
- *     otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.
- *
- *     Note that you can also require the directive's own controller - it will be made available like
- *     any other controller.
- *
- *   * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
- *     This is the same as the `$transclude` parameter of directive controllers,
- *     see {@link ng.$compile#-controller- the controller section for details}.
- *     `function([scope], cloneLinkingFn, futureParentElement)`.
- *
- * #### Pre-linking function
- *
- * Executed before the child elements are linked. Not safe to do DOM transformation since the
- * compiler linking function will fail to locate the correct elements for linking.
- *
- * #### Post-linking function
- *
- * Executed after the child elements are linked.
- *
- * Note that child elements that contain `templateUrl` directives will not have been compiled
- * and linked since they are waiting for their template to load asynchronously and their own
- * compilation and linking has been suspended until that occurs.
- *
- * It is safe to do DOM transformation in the post-linking function on elements that are not waiting
- * for their async templates to be resolved.
- *
- *
- * ### Transclusion
- *
- * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and
- * copying them to another part of the DOM, while maintaining their connection to the original AngularJS
- * scope from where they were taken.
- *
- * Transclusion is used (often with {@link ngTransclude}) to insert the
- * original contents of a directive's element into a specified place in the template of the directive.
- * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
- * content has access to the properties on the scope from which it was taken, even if the directive
- * has isolated scope.
- * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
- *
- * This makes it possible for the widget to have private state for its template, while the transcluded
- * content has access to its originating scope.
- *
- * <div class="alert alert-warning">
- * **Note:** When testing an element transclude directive you must not place the directive at the root of the
- * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
- * Testing Transclusion Directives}.
- * </div>
- *
- * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the
- * directive's element, the entire element or multiple parts of the element contents:
- *
- * * `true` - transclude the content (i.e. the child nodes) of the directive's element.
- * * `'element'` - transclude the whole of the directive's element including any directives on this
- *   element that defined at a lower priority than this directive. When used, the `template`
- *   property is ignored.
- * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template.
- *
- * **Mult-slot transclusion** is declared by providing an object for the `transclude` property.
- *
- * This object is a map where the keys are the name of the slot to fill and the value is an element selector
- * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)
- * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).
- *
- * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}
- *
- * If the element selector is prefixed with a `?` then that slot is optional.
- *
- * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `<my-custom-element>` elements to
- * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.
- *
- * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements
- * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call
- * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and
- * injectable into the directive's controller.
- *
- *
- * #### Transclusion Functions
- *
- * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
- * function** to the directive's `link` function and `controller`. This transclusion function is a special
- * **linking function** that will return the compiled contents linked to a new transclusion scope.
- *
- * <div class="alert alert-info">
- * If you are just using {@link ngTransclude} then you don't need to worry about this function, since
- * ngTransclude will deal with it for us.
- * </div>
- *
- * If you want to manually control the insertion and removal of the transcluded content in your directive
- * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
- * object that contains the compiled DOM, which is linked to the correct transclusion scope.
- *
- * When you call a transclusion function you can pass in a **clone attach function**. This function accepts
- * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
- * content and the `scope` is the newly created transclusion scope, which the clone will be linked to.
- *
- * <div class="alert alert-info">
- * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function
- * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
- * </div>
- *
- * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
- * attach function**:
- *
- * ```js
- * var transcludedContent, transclusionScope;
- *
- * $transclude(function(clone, scope) {
- *   element.append(clone);
- *   transcludedContent = clone;
- *   transclusionScope = scope;
- * });
- * ```
- *
- * Later, if you want to remove the transcluded content from your DOM then you should also destroy the
- * associated transclusion scope:
- *
- * ```js
- * transcludedContent.remove();
- * transclusionScope.$destroy();
- * ```
- *
- * <div class="alert alert-info">
- * **Best Practice**: if you intend to add and remove transcluded content manually in your directive
- * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),
- * then you are also responsible for calling `$destroy` on the transclusion scope.
- * </div>
- *
- * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
- * automatically destroy their transcluded clones as necessary so you do not need to worry about this if
- * you are simply using {@link ngTransclude} to inject the transclusion into your directive.
- *
- *
- * #### Transclusion Scopes
- *
- * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
- * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
- * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
- * was taken.
- *
- * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
- * like this:
- *
- * ```html
- * <div ng-app>
- *   <div isolate>
- *     <div transclusion>
- *     </div>
- *   </div>
- * </div>
- * ```
- *
- * The `$parent` scope hierarchy will look like this:
- *
-   ```
-   - $rootScope
-     - isolate
-       - transclusion
-   ```
- *
- * but the scopes will inherit prototypically from different scopes to their `$parent`.
- *
-   ```
-   - $rootScope
-     - transclusion
-   - isolate
-   ```
- *
- *
- * ### Attributes
- *
- * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
- * `link()` or `compile()` functions. It has a variety of uses.
- *
- * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways:
- *   'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access
- *   to the attributes.
- *
- * * *Directive inter-communication:* All directives share the same instance of the attributes
- *   object which allows the directives to use the attributes object as inter directive
- *   communication.
- *
- * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
- *   allowing other directives to read the interpolated value.
- *
- * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
- *   that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
- *   the only way to easily get the actual value because during the linking phase the interpolation
- *   hasn't been evaluated yet and so the value is at this time set to `undefined`.
- *
- * ```js
- * function linkingFn(scope, elm, attrs, ctrl) {
- *   // get the attribute value
- *   console.log(attrs.ngModel);
- *
- *   // change the attribute
- *   attrs.$set('ngModel', 'new value');
- *
- *   // observe changes to interpolated attribute
- *   attrs.$observe('ngModel', function(value) {
- *     console.log('ngModel has changed value to ' + value);
- *   });
- * }
- * ```
- *
- * ## Example
- *
- * <div class="alert alert-warning">
- * **Note**: Typically directives are registered with `module.directive`. The example below is
- * to illustrate how `$compile` works.
- * </div>
- *
- <example module="compileExample" name="compile">
-   <file name="index.html">
-    <script>
-      angular.module('compileExample', [], function($compileProvider) {
-        // configure new 'compile' directive by passing a directive

-        $compileProvider.directive('compile', function($compile) {
-          // directive factory creates a link function
-          return function(scope, element, attrs) {
-            scope.$watch(
-              function(scope) {
-                 // watch the 'compile' expression for changes
-                return scope.$eval(attrs.compile);
-              },
-              function(value) {
-                // when the 'compile' expression changes

- *
- * @param {number} maxPriority only apply directives lower than given priority (Only effects the

- * (a DOM element/tree) to a scope. Where:
- *
- *  * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
- *  * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
- *  `template` and call the `cloneAttachFn` function allowing the caller to attach the
- *  cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
- *  called as: <br/> `cloneAttachFn(clonedElement, scope)` where:
- *
- *      * `clonedElement` - is a clone of the original `element` passed into the compiler.
- *      * `scope` - is the current scope with which the linking function is working with.
- *
- *  * `options` - An optional object hash with linking options. If `options` is provided, then the following
- *  keys may be used to control linking behavior:
- *
- *      * `parentBoundTranscludeFn` - the transclude function made available to
- *        directives; if given, it will be passed through to the link functions of
- *        directives found in `element` during compilation.
- *      * `transcludeControllers` - an object hash with keys that map controller names
- *        to a hash with the key `instance`, which maps to the controller instance;
- *        if given, it will make the controllers available to directives on the compileNode:
- *        ```
- *        {
- *          parent: {
- *            instance: parentControllerInstance
- *          }
- *        }
- *        ```
- *      * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add
- *        the cloned elements; only needed for transcludes that are allowed to contain non html
- *        elements (e.g. SVG elements). See also the directive.controller property.
- *
- * Calling the linking function returns the element of the template. It is either the original
- * element passed in, or the clone of the element if the `cloneAttachFn` is provided.
- *
- * After linking the view is not updated until after a call to $digest which typically is done by
- * Angular automatically.
- *
- * If you need access to the bound view, there are two ways to do it:
- *
- * - If you are not asking the linking function to clone the template, create the DOM element(s)
- *   before you send them to the compiler and keep this reference around.
- *   ```js
- *     var element = $compile('<p>{{total}}</p>')(scope);
- *   ```
- *
- * - if on the other hand, you need the element to be cloned, the view reference from the original
- *   example would not point to the clone, but rather to the original template that was cloned. In
- *   this case, you can access the clone via the cloneAttachFn:
- *   ```js
- *     var templateElement = angular.element('<p>{{total}}</p>'),
- *         scope = ....;
- *
- *     var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
- *       //attach the clone to DOM document at the right place
- *     });
- *
- *     //now we have reference to the cloned DOM via `clonedElement`
- *   ```
- *
- *

- * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

- * ### Double Compilation
- *
-   Double compilation occurs when an already compiled part of the DOM gets
-   compiled again. This is an undesired effect and can lead to misbehaving directives, performance issues,
-   and memory leaks. Refer to the Compiler Guide {@link guide/compiler#double-compilation-and-how-to-avoid-it
-   section on double compilation} for an in-depth explanation and ways to avoid it.

-   * @description
-   * Register a **component definition** with the compiler. This is a shorthand for registering a special
-   * type of directive, which represents a self-contained UI component in your application. Such components
-   * are always isolated (i.e. `scope: {}`) and are always restricted to elements (i.e. `restrict: 'E'`).
-   *
-   * Component definitions are very simple and do not require as much configuration as defining general
-   * directives. Component definitions usually consist only of a template and a controller backing it.
-   *
-   * In order to make the definition easier, components enforce best practices like use of `controllerAs`,
-   * `bindToController`. They always have **isolate scope** and are restricted to elements.
-   *
-   * Here are a few examples of how you would usually define components:
-   *
-   * ```js
-   *   var myMod = angular.module(...);
-   *   myMod.component('myComp', {
-   *     template: '<div>My name is {{$ctrl.name}}</div>',
-   *     controller: function() {
-   *       this.name = 'shahar';
-   *     }
-   *   });
-   *
-   *   myMod.component('myComp', {
-   *     template: '<div>My name is {{$ctrl.name}}</div>',
-   *     bindings: {name: '@'}
-   *   });
-   *
-   *   myMod.component('myComp', {
-   *     templateUrl: 'views/my-comp.html',
-   *     controller: 'MyCtrl',
-   *     controllerAs: 'ctrl',
-   *     bindings: {name: '@'}
-   *   });
-   *
-   * ```
-   * For more examples, and an in-depth guide, see the {@link guide/component component guide}.

- * Any uncaught exception in angular expressions is delegated to this service.

- * the browser console.
- *
- * In unit tests, if `angular-mocks.js` is loaded, this service is overridden by
- * {@link ngMock.$exceptionHandler mock $exceptionHandler} which aids in testing.
- *
- * ## Example:
- *
- * The example below will overwrite the default `$exceptionHandler` in order to (a) log uncaught
- * errors to the backend for later inspection by the developers and (b) to use `$log.warn()` instead
- * of `$log.error()`.
- *
- * ```js
- *   angular.
- *     module('exceptionOverwrite', []).
- *     factory('$exceptionHandler', ['$log', 'logErrorsToBackend', function($log, logErrorsToBackend) {
- *       return function myExceptionHandler(exception, cause) {

- *         $log.warn(exception, cause);
- *       };
- *     }]);
- * ```
- *
- * <hr />
- * Note, that code executed in event-listeners (even those registered using jqLite's `on`/`bind`
- * methods) does not delegate exceptions to the {@link ng.$exceptionHandler $exceptionHandler}
- * (unless executed during a digest).
- *
- * If you wish, you can manually delegate exceptions, e.g.
- * `try { ... } catch(e) { $exceptionHandler(e); }`
- *

-     * @description
-     * The `$http` service is a core Angular service that facilitates communication with the remote
-     * HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
-     * object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
-     *
-     * For unit testing applications that use `$http` service, see
-     * {@link ngMock.$httpBackend $httpBackend mock}.
-     *
-     * For a higher level of abstraction, please check out the {@link ngResource.$resource
-     * $resource} service.
-     *
-     * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
-     * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
-     * it is important to familiarize yourself with these APIs and the guarantees they provide.
-     *
-     *
-     * ## General usage
-     * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} —
-     * that is used to generate an HTTP request and returns  a {@link ng.$q promise}.
-     *
-     * ```js
-     *   // Simple GET request example:
-     *   $http({
-     *     method: 'GET',
-     *     url: '/someUrl'
-     *   }).then(function successCallback(response) {
-     *       // this callback will be called asynchronously
-     *       // when the response is available
-     *     }, function errorCallback(response) {
-     *       // called asynchronously if an error occurs
-     *       // or server returns response with an error status.
-     *     });
-     * ```
-     *
-     * The response object has these properties:
-     *
-     *   - **data** – `{string|Object}` – The response body transformed with the transform
-     *     functions.
-     *   - **status** – `{number}` – HTTP status code of the response.
-     *   - **headers** – `{function([headerName])}` – Header getter function.
-     *   - **config** – `{Object}` – The configuration object that was used to generate the request.
-     *   - **statusText** – `{string}` – HTTP status text of the response.
-     *
-     * A response status code between 200 and 299 is considered a success status and will result in
-     * the success callback being called. Any response status code outside of that range is
-     * considered an error status and will result in the error callback being called.
-     * Also, status codes less than -1 are normalized to zero. -1 usually means the request was
-     * aborted, e.g. using a `config.timeout`.
-     * Note that if the response is a redirect, XMLHttpRequest will transparently follow it, meaning
-     * that the outcome (success or error) will be determined by the final response status code.
-     *
-     *
-     * ## Shortcut methods
-     *
-     * Shortcut methods are also available. All shortcut methods require passing in the URL, and
-     * request data must be passed in for POST/PUT requests. An optional config can be passed as the
-     * last argument.
-     *
-     * ```js
-     *   $http.get('/someUrl', config).then(successCallback, errorCallback);
-     *   $http.post('/someUrl', data, config).then(successCallback, errorCallback);
-     * ```
-     *
-     * Complete list of shortcut methods:
-     *
-     * - {@link ng.$http#get $http.get}
-     * - {@link ng.$http#head $http.head}
-     * - {@link ng.$http#post $http.post}
-     * - {@link ng.$http#put $http.put}
-     * - {@link ng.$http#delete $http.delete}
-     * - {@link ng.$http#jsonp $http.jsonp}
-     * - {@link ng.$http#patch $http.patch}
-     *
-     *
-     * ## Writing Unit Tests that use $http
-     * When unit testing (using {@link ngMock ngMock}), it is necessary to call
-     * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
-     * request using trained responses.
-     *
-     * ```
-     * $httpBackend.expectGET(...);
-     * $http.get(...);
-     * $httpBackend.flush();
-     * ```
-     *
-     * ## Setting HTTP Headers
-     *
-     * The $http service will automatically add certain HTTP headers to all requests. These defaults
-     * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
-     * object, which currently contains this default configuration:
-     *
-     * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
-     *   - <code>Accept: application/json, text/plain, \*&#65279;/&#65279;\*</code>
-     * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
-     *   - `Content-Type: application/json`
-     * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
-     *   - `Content-Type: application/json`
-     *
-     * To add or overwrite these defaults, simply add or remove a property from these configuration
-     * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
-     * with the lowercased HTTP method name as the key, e.g.
-     * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.
-     *
-     * The defaults can also be set at runtime via the `$http.defaults` object in the same
-     * fashion. For example:
-     *
-     * ```
-     * module.run(function($http) {
-     *   $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w';
-     * });
-     * ```
-     *
-     * In addition, you can supply a `headers` property in the config object passed when
-     * calling `$http(config)`, which overrides the defaults without changing them globally.
-     *
-     * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,
-     * Use the `headers` property, setting the desired header to `undefined`. For example:
-     *
-     * ```js
-     * var req = {
-     *  method: 'POST',
-     *  url: 'http://example.com',
-     *  headers: {
-     *    'Content-Type': undefined
-     *  },
-     *  data: { test: 'test' }
-     * }
-     *
-     * $http(req).then(function(){...}, function(){...});
-     * ```
-     *
-     * ## Transforming Requests and Responses
-     *
-     * Both requests and responses can be transformed using transformation functions: `transformRequest`
-     * and `transformResponse`. These properties can be a single function that returns
-     * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
-     * which allows you to `push` or `unshift` a new transformation function into the transformation chain.
-     *
-     * <div class="alert alert-warning">
-     * **Note:** Angular does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.
-     * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).
-     * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest
-     * function will be reflected on the scope and in any templates where the object is data-bound.
-     * To prevent this, transform functions should have no side-effects.
-     * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.
-     * </div>
-     *
-     * ### Default Transformations
-     *
-     * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
-     * `defaults.transformResponse` properties. If a request does not provide its own transformations
-     * then these will be applied.
-     *
-     * You can augment or replace the default transformations by modifying these properties by adding to or
-     * replacing the array.
-     *
-     * Angular provides the following default transformations:
-     *
-     * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):
-     *
-     * - If the `data` property of the request configuration object contains an object, serialize it
-     *   into JSON format.
-     *
-     * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):
-     *
-     *  - If XSRF prefix is detected, strip it (see Security Considerations section below).
-     *  - If JSON response is detected, deserialize it using a JSON parser.
-     *
-     *
-     * ### Overriding the Default Transformations Per Request
-     *
-     * If you wish to override the request/response transformations only for a single request then provide
-     * `transformRequest` and/or `transformResponse` properties on the configuration object passed
-     * into `$http`.
-     *
-     * Note that if you provide these properties on the config object the default transformations will be
-     * overwritten. If you wish to augment the default transformations then you must include them in your
-     * local transformation array.
-     *
-     * The following code demonstrates adding a new response transformation to be run after the default response
-     * transformations have been run.
-     *
-     * ```js
-     * function appendTransform(defaults, transform) {
-     *
-     *   // We can't guarantee that the default transformation is an array
-     *   defaults = angular.isArray(defaults) ? defaults : [defaults];
-     *
-     *   // Append the new transformation to the defaults
-     *   return defaults.concat(transform);
-     * }
-     *
-     * $http({
-     *   url: '...',
-     *   method: 'GET',
-     *   transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
-     *     return doTransform(value);
-     *   })
-     * });
-     * ```
-     *
-     *
-     * ## Caching
-     *
-     * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must
-     * set the config.cache value or the default cache value to TRUE or to a cache object (created
-     * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes
-     * precedence over the default cache value.
-     *
-     * In order to:
-     *   * cache all responses - set the default cache value to TRUE or to a cache object
-     *   * cache a specific response - set config.cache value to TRUE or to a cache object
-     *
-     * If caching is enabled, but neither the default cache nor config.cache are set to a cache object,
-     * then the default `$cacheFactory("$http")` object is used.
-     *
-     * The default cache value can be set by updating the
-     * {@link ng.$http#defaults `$http.defaults.cache`} property or the
-     * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.
-     *
-     * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using
-     * the relevant cache object. The next time the same request is made, the response is returned
-     * from the cache without sending a request to the server.
-     *
-     * Take note that:
-     *
-     *   * Only GET and JSONP requests are cached.
-     *   * The cache key is the request URL including search parameters; headers are not considered.
-     *   * Cached responses are returned asynchronously, in the same way as responses from the server.
-     *   * If multiple identical requests are made using the same cache, which is not yet populated,
-     *     one request will be made to the server and remaining requests will return the same response.
-     *   * A cache-control header on the response does not affect if or how responses are cached.
-     *
-     *
-     * ## Interceptors
-     *
-     * Before you start creating interceptors, be sure to understand the
-     * {@link ng.$q $q and deferred/promise APIs}.
-     *
-     * For purposes of global error handling, authentication, or any kind of synchronous or
-     * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
-     * able to intercept requests before they are handed to the server and
-     * responses before they are handed over to the application code that
-     * initiated these requests. The interceptors leverage the {@link ng.$q
-     * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
-     *
-     * The interceptors are service factories that are registered with the `$httpProvider` by
-     * adding them to the `$httpProvider.interceptors` array. The factory is called and
-     * injected with dependencies (if specified) and returns the interceptor.
-     *
-     * There are two kinds of interceptors (and two kinds of rejection interceptors):
-     *
-     *   * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to
-     *     modify the `config` object or create a new one. The function needs to return the `config`
-     *     object directly, or a promise containing the `config` or a new `config` object.
-     *   * `requestError`: interceptor gets called when a previous interceptor threw an error or
-     *     resolved with a rejection.
-     *   * `response`: interceptors get called with http `response` object. The function is free to
-     *     modify the `response` object or create a new one. The function needs to return the `response`
-     *     object directly, or as a promise containing the `response` or a new `response` object.
-     *   * `responseError`: interceptor gets called when a previous interceptor threw an error or
-     *     resolved with a rejection.
-     *
-     *
-     * ```js
-     *   // register the interceptor as a service
-     *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
-     *     return {
-     *       // optional method
-     *       'request': function(config) {
-     *         // do something on success
-     *         return config;
-     *       },
-     *
-     *       // optional method
-     *      'requestError': function(rejection) {
-     *         // do something on error
-     *         if (canRecover(rejection)) {
-     *           return responseOrNewPromise
-     *         }
-     *         return $q.reject(rejection);
-     *       },
-     *
-     *
-     *
-     *       // optional method
-     *       'response': function(response) {
-     *         // do something on success
-     *         return response;
-     *       },
-     *
-     *       // optional method
-     *      'responseError': function(rejection) {
-     *         // do something on error
-     *         if (canRecover(rejection)) {
-     *           return responseOrNewPromise
-     *         }
-     *         return $q.reject(rejection);
-     *       }
-     *     };
-     *   });
-     *
-     *   $httpProvider.interceptors.push('myHttpInterceptor');
-     *
-     *
-     *   // alternatively, register the interceptor via an anonymous factory
-     *   $httpProvider.interceptors.push(function($q, dependency1, dependency2) {
-     *     return {
-     *      'request': function(config) {
-     *          // same as above
-     *       },
-     *
-     *       'response': function(response) {
-     *          // same as above
-     *       }
-     *     };
-     *   });
-     * ```
-     *
-     * ## Security Considerations
-     *
-     * When designing web applications, consider security threats from:
-     *
-     * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
-     * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
-     *
-     * Both server and the client must cooperate in order to eliminate these threats. Angular comes
-     * pre-configured with strategies that address these issues, but for this to work backend server
-     * cooperation is required.
-     *
-     * ### JSON Vulnerability Protection
-     *
-     * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
-     * allows third party website to turn your JSON resource URL into
-     * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
-     * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
-     * Angular will automatically strip the prefix before processing it as JSON.
-     *
-     * For example if your server needs to return:
-     * ```js
-     * ['one','two']
-     * ```
-     *
-     * which is vulnerable to attack, your server can return:
-     * ```js
-     * )]}',
-     * ['one','two']
-     * ```
-     *
-     * Angular will strip the prefix, before processing the JSON.
-     *
-     *
-     * ### Cross Site Request Forgery (XSRF) Protection
-     *
-     * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by
-     * which the attacker can trick an authenticated user into unknowingly executing actions on your
-     * website. Angular provides a mechanism to counter XSRF. When performing XHR requests, the
-     * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP
-     * header (`X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read the
-     * cookie, your server can be assured that the XHR came from JavaScript running on your domain.
-     * The header will not be set for cross-domain requests.
-     *
-     * To take advantage of this, your server needs to set a token in a JavaScript readable session
-     * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
-     * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
-     * that only JavaScript running on your domain could have sent the request. The token must be
-     * unique for each user and must be verifiable by the server (to prevent the JavaScript from
-     * making up its own tokens). We recommend that the token is a digest of your site's
-     * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography&#41;)
-     * for added security.
-     *
-     * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
-     * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,
-     * or the per-request config object.
-     *
-     * In order to prevent collisions in environments where multiple Angular apps share the
-     * same domain or subdomain, we recommend that each application uses unique cookie name.
-     *
-     * @param {object} config Object describing the request to be made and how it should be
-     *    processed. The object has following properties:
-     *
-     *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
-     *    - **url** – `{string|TrustedObject}` – Absolute or relative URL of the resource that is being requested;
-     *      or an object created by a call to `$sce.trustAsResourceUrl(url)`.
-     *    - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be serialized
-     *      with the `paramSerializer` and appended as GET parameters.
-     *    - **data** – `{string|Object}` – Data to be sent as the request message data.
-     *    - **headers** – `{Object}` – Map of strings or functions which return strings representing
-     *      HTTP headers to send to the server. If the return value of a function is null, the
-     *      header will not be sent. Functions accept a config object as an argument.
-     *    - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object.
-     *      To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`.
-     *      The handler will be called in the context of a `$apply` block.
-     *    - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload

-     *      `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
-     *      transform function or an array of such functions. The transform function takes the http
-     *      request body and headers and returns its transformed (typically serialized) version.

-     *    - **paramSerializer** - `{string|function(Object<string,string>):string}` - A function used to
-     *      prepare the string representation of request parameters (specified as an object).
-     *      If specified as string, it is interpreted as function registered with the
-     *      {@link $injector $injector}, which means you can create your own serializer
-     *      by registering it as a {@link auto.$provide#service service}.
-     *      The default serializer is the {@link $httpParamSerializer $httpParamSerializer};

-     *      See {@link $http#caching $http Caching} for more information.
-     *    - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
-     *      that should abort the request when resolved.
-     *    - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
-     *      XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
-     *      for more information.

-     *
-     * @returns {HttpPromise} Returns a {@link ng.$q `Promise}` that will be resolved to a response object
-     *                        when the request succeeds or fails.
-     *

-     * @description
-     *
-     * Compiles a string with markup into an interpolation function. This service is used by the
-     * HTML {@link ng.$compile $compile} service for data binding. See
-     * {@link ng.$interpolateProvider $interpolateProvider} for configuring the
-     * interpolation markup.
-     *
-     *
-     * ```js
-     *   var $interpolate = ...; // injected
-     *   var exp = $interpolate('Hello {{name | uppercase}}!');
-     *   expect(exp({name:'Angular'})).toEqual('Hello ANGULAR!');
-     * ```
-     *
-     * `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is
-     * `true`, the interpolation function will return `undefined` unless all embedded expressions
-     * evaluate to a value other than `undefined`.
-     *
-     * ```js
-     *   var $interpolate = ...; // injected
-     *   var context = {greeting: 'Hello', name: undefined };
-     *
-     *   // default "forgiving" mode
-     *   var exp = $interpolate('{{greeting}} {{name}}!');
-     *   expect(exp(context)).toEqual('Hello !');
-     *
-     *   // "allOrNothing" mode
-     *   exp = $interpolate('{{greeting}} {{name}}!', false, null, true);
-     *   expect(exp(context)).toBeUndefined();
-     *   context.name = 'Angular';
-     *   expect(exp(context)).toEqual('Hello Angular!');
-     * ```
-     *
-     * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
-     *
-     * #### Escaped Interpolation
-     * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
-     * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
-     * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
-     * or binding.
-     *
-     * This enables web-servers to prevent script injection attacks and defacing attacks, to some
-     * degree, while also enabling code examples to work without relying on the
-     * {@link ng.directive:ngNonBindable ngNonBindable} directive.
-     *
-     * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
-     * replacing angle brackets (&lt;, &gt;) with &amp;lt; and &amp;gt; respectively, and replacing all
-     * interpolation start/end markers with their escaped counterparts.**
-     *
-     * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
-     * output when the $interpolate service processes the text. So, for HTML elements interpolated
-     * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
-     * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
-     * this is typically useful only when user-data is used in rendering a template from the server, or
-     * when otherwise untrusted data is used by a directive.
-     *
-     * <example name="interpolation">
-     *  <file name="index.html">
-     *    <div ng-init="username='A user'">
-     *      <p ng-init="apptitle='Escaping demo'">{{apptitle}}: \{\{ username = "defaced value"; \}\}
-     *        </p>
-     *      <p><strong>{{username}}</strong> attempts to inject code which will deface the
-     *        application, but fails to accomplish their task, because the server has correctly
-     *        escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
-     *        characters.</p>
-     *      <p>Instead, the result of the attempted script injection is visible, and can be removed
-     *        from the database by an administrator.</p>
-     *    </div>
-     *  </file>
-     * </example>
-     *
-     * @knownIssue
-     * It is currently not possible for an interpolated expression to contain the interpolation end
-     * symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e.
-     * an interpolated expression consisting of a single-quote (`'`) and the `' }}` string.
-     *
-     * @knownIssue
-     * All directives and components must use the standard `{{` `}}` interpolation symbols
-     * in their templates. If you change the application interpolation symbols the {@link $compile}
-     * service will attempt to denormalize the standard symbols to the custom symbols.
-     * The denormalization process is not clever enough to know not to replace instances of the standard
-     * symbols where they would not normally be treated as interpolation symbols. For example in the following
-     * code snippet the closing braces of the literal object will get incorrectly denormalized:
-     *
-     * ```
-     * <div data-context='{"context":{"id":3,"type":"page"}}">
-     * ```
-     *
-     * The workaround is to ensure that such instances are separated by whitespace:
-     * ```
-     * <div data-context='{"context":{"id":3,"type":"page"} }">
-     * ```

-      * milliseconds.
-      *
-      * The return value of registering an interval function is a promise. This promise will be
-      * notified upon each tick of the interval, and will be resolved after `count` iterations, or
-      * run indefinitely if `count` is not defined. The value of the notification will be the
-      * number of iterations that have run.
-      * To cancel an interval, call `$interval.cancel(promise)`.
-      *
-      * In tests you can use {@link ngMock.$interval#flush `$interval.flush(millis)`} to
-      * move forward by `millis` milliseconds and trigger any functions scheduled to run in that
-      * time.
-      *
-      * <div class="alert alert-warning">
-      * **Note**: Intervals created by this service must be explicitly destroyed when you are finished
-      * with them.  In particular they are not automatically destroyed when a controller's scope or a
-      * directive's element are destroyed.
-      * You should take this into consideration and make sure to always cancel the interval at the
-      * appropriate moment.  See the example below for more details on how and when to do this.
-      * </div>
-      *
-      * @param {function()} fn A function that should be called repeatedly. If no additional arguments
-      *   are passed (see below), the function is called with the current iteration count.
-      * @param {number} delay Number of milliseconds between each function call.
-      * @param {number=} [count=0] Number of times to repeat. If not set, or 0, will repeat
-      *   indefinitely.
-      * @param {boolean=} [invokeApply=true] If set to `false` skips model dirty checking, otherwise
-      *   will invoke `fn` within the {@link ng.$rootScope.Scope#$apply $apply} block.
-      * @param {...*=} Pass additional parameters to the executed function.

- * The $location service parses the URL in the browser address bar (based on the
- * [window.location](https://developer.mozilla.org/en/window.location)) and makes the URL
- * available to your application. Changes to the URL in the address bar are reflected into
- * $location service and changes to $location are reflected into the browser address bar.
- *
- * **The $location service:**
- *
- * - Exposes the current URL in the browser address bar, so you can
- *   - Watch and observe the URL.
- *   - Change the URL.
- * - Synchronizes the URL with the browser when the user
- *   - Changes the address bar.
- *   - Clicks the back or forward button (or clicks a History link).
- *   - Clicks on a link.
- * - Represents the URL object as a set of methods (protocol, host, port, path, search, hash).

-/**
- * @ngdoc service
- * @name $q
- * @requires $rootScope
- *
- * @description
- * A service that helps you run functions asynchronously, and use their return values (or exceptions)
- * when they are done processing.
- *
- * This is a [Promises/A+](https://promisesaplus.com/)-compliant implementation of promises/deferred
- * objects inspired by [Kris Kowal's Q](https://github.com/kriskowal/q).
- *
- * $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred
- * implementations, and the other which resembles ES6 (ES2015) promises to some degree.
- *
- * # $q constructor
- *
- * The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`
- * function as the first argument. This is similar to the native Promise implementation from ES6,
- * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
- *
- * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are
- * available yet.
- *
- * It can be used like so:
- *
- * ```js
- *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`
- *   // are available in the current lexical scope (they could have been injected or passed in).
- *
- *   function asyncGreet(name) {
- *     // perform some asynchronous operation, resolve or reject the promise when appropriate.
- *     return $q(function(resolve, reject) {
- *       setTimeout(function() {
- *         if (okToGreet(name)) {
- *           resolve('Hello, ' + name + '!');
- *         } else {
- *           reject('Greeting ' + name + ' is not allowed.');
- *         }
- *       }, 1000);
- *     });
- *   }
- *
- *   var promise = asyncGreet('Robin Hood');
- *   promise.then(function(greeting) {
- *     alert('Success: ' + greeting);
- *   }, function(reason) {
- *     alert('Failed: ' + reason);
- *   });
- * ```
- *
- * Note: progress/notify callbacks are not currently supported via the ES6-style interface.
- *
- * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise.
- *
- * However, the more traditional CommonJS-style usage is still available, and documented below.
- *
- * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
- * interface for interacting with an object that represents the result of an action that is
- * performed asynchronously, and may or may not be finished at any given point in time.
- *
- * From the perspective of dealing with error handling, deferred and promise APIs are to
- * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
- *
- * ```js
- *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`
- *   // are available in the current lexical scope (they could have been injected or passed in).
- *
- *   function asyncGreet(name) {
- *     var deferred = $q.defer();
- *
- *     setTimeout(function() {
- *       deferred.notify('About to greet ' + name + '.');
- *
- *       if (okToGreet(name)) {
- *         deferred.resolve('Hello, ' + name + '!');
- *       } else {
- *         deferred.reject('Greeting ' + name + ' is not allowed.');
- *       }
- *     }, 1000);
- *
- *     return deferred.promise;
- *   }
- *
- *   var promise = asyncGreet('Robin Hood');
- *   promise.then(function(greeting) {
- *     alert('Success: ' + greeting);
- *   }, function(reason) {
- *     alert('Failed: ' + reason);
- *   }, function(update) {
- *     alert('Got notification: ' + update);
- *   });
- * ```
- *
- * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
- * comes in the way of guarantees that promise and deferred APIs make, see
- * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
- *
- * Additionally the promise api allows for composition that is very hard to do with the
- * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
- * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
- * section on serial or parallel joining of promises.
- *
- * # The Deferred API
- *
- * A new instance of deferred is constructed by calling `$q.defer()`.
- *
- * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
- * that can be used for signaling the successful or unsuccessful completion, as well as the status
- * of the task.
- *
- * **Methods**
- *
- * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
- *   constructed via `$q.reject`, the promise will be rejected instead.
- * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
- *   resolving it with a rejection constructed via `$q.reject`.
- * - `notify(value)` - provides updates on the status of the promise's execution. This may be called
- *   multiple times before the promise is either resolved or rejected.
- *
- * **Properties**
- *
- * - promise – `{Promise}` – promise object associated with this deferred.
- *
- *
- * # The Promise API
- *
- * A new promise instance is created when a deferred instance is created and can be retrieved by
- * calling `deferred.promise`.
- *
- * The purpose of the promise object is to allow for interested parties to get access to the result
- * of the deferred task when it completes.
- *
- * **Methods**
- *
- * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or
- *   will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
- *   as soon as the result is available. The callbacks are called with a single argument: the result
- *   or rejection reason. Additionally, the notify callback may be called zero or more times to
- *   provide a progress indication, before the promise is resolved or rejected.
- *
- *   This method *returns a new promise* which is resolved or rejected via the return value of the
- *   `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved
- *   with the value which is resolved in that promise using
- *   [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).
- *   It also notifies via the return value of the `notifyCallback` method. The promise cannot be
- *   resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback
- *   arguments are optional.
- *
- * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
- *
- * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,
- *   but to do so without modifying the final value. This is useful to release resources or do some
- *   clean-up that needs to be done whether the promise was rejected or resolved. See the [full
- *   specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
- *   more information.
- *
- * # Chaining promises
- *
- * Because calling the `then` method of a promise returns a new derived promise, it is easily
- * possible to create a chain of promises:
- *
- * ```js
- *   promiseB = promiseA.then(function(result) {
- *     return result + 1;
- *   });
- *
- *   // promiseB will be resolved immediately after promiseA is resolved and its value
- *   // will be the result of promiseA incremented by 1
- * ```
- *
- * It is possible to create chains of any length and since a promise can be resolved with another
- * promise (which will defer its resolution further), it is possible to pause/defer resolution of
- * the promises at any point in the chain. This makes it possible to implement powerful APIs like
- * $http's response interceptors.
- *
- *
- * # Differences between Kris Kowal's Q and $q
- *
- *  There are two main differences:
- *
- * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
- *   mechanism in angular, which means faster propagation of resolution or rejection into your
- *   models and avoiding unnecessary browser repaints, which would result in flickering UI.
- * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
- *   all the important functionality needed for common async tasks.
- *
- * # Testing
- *
- *  ```js
- *    it('should simulate promise', inject(function($q, $rootScope) {
- *      var deferred = $q.defer();
- *      var promise = deferred.promise;
- *      var resolvedValue;
- *
- *      promise.then(function(value) { resolvedValue = value; });
- *      expect(resolvedValue).toBeUndefined();
- *
- *      // Simulate resolving of promise
- *      deferred.resolve(123);
- *      // Note that the 'then' function does not get called synchronously.
- *      // This is because we want the promise API to always be async, whether or not
- *      // it got called synchronously or asynchronously.
- *      expect(resolvedValue).toBeUndefined();
- *
- *      // Propagate promise resolution to 'then' functions using $apply().
- *      $rootScope.$apply();
- *      expect(resolvedValue).toEqual(123);
- *    }));
- *  ```
- *
- * @param {function(function, function)} resolver Function which is responsible for resolving or
- *   rejecting the newly created promise. The first parameter is a function which resolves the
- *   promise, the second parameter is a function which rejects the promise.
- *
- * @returns {Promise} The newly created promise.

-   * Creates a promise that is resolved as rejected with the specified `reason`. This api should be
-   * used to forward rejection in a chain of promises. If you are dealing with the last promise in
-   * a promise chain, you don't need to worry about it.

-   * a promise error callback and you want to forward the error to the promise derived from the
-   * current promise, you have to "rethrow" the error by returning a rejection constructed via
-   * `reject`.
-   *
-   * ```js
-   *   promiseB = promiseA.then(function(result) {
-   *     // success: do something and resolve promiseB
-   *     //          with the old or a new result
-   *     return result;
-   *   }, function(reason) {
-   *     // error: handle the error if possible and
-   *     //        resolve promiseB with newPromiseOrValue,
-   *     //        otherwise forward the rejection to promiseB
-   *     if (canHandle(reason)) {
-   *      // handle the error and recover
-   *      return newPromiseOrValue;
-   *     }

-/**
- * DESIGN NOTES
- *
- * The design decisions behind the scope are heavily favored for speed and memory consumption.
- *
- * The typical use of scope is to watch the expressions, which most of the time return the same
- * value as last time so we optimize the operation.
- *
- * Closures construction is expensive in terms of speed as well as memory:
- *   - No closures, instead use prototypical inheritance for API
- *   - Internal state needs to be stored on scope directly, which means that private state is
- *     exposed as $$____ properties
- *
- * Loop operations are optimized by using while(count--) { ... }
- *   - This means that in order to keep the same order of execution as addition we have to add
- *     items to the array at the beginning (unshift) instead of at the end (push)
- *
- * Child scopes are created and removed often
- *   - Using an array would be slow since inserts in the middle are expensive; so we use linked lists
- *
- * There are fewer watches than observers. This is why you don't want the observer to be implemented
- * in the same way as watch. Watch requires return of the initialization function which is expensive
- * to construct.

-       * @name $rootScope.Scope#$watch
-       * @kind function
-       *
-       * @description
-       * Registers a `listener` callback to be executed whenever the `watchExpression` changes.
-       *
-       * - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest
-       *   $digest()} and should return the value that will be watched. (`watchExpression` should not change
-       *   its value when executed multiple times with the same input because it may be executed multiple
-       *   times by {@link ng.$rootScope.Scope#$digest $digest()}. That is, `watchExpression` should be
-       *   [idempotent](http://en.wikipedia.org/wiki/Idempotence).)
-       * - The `listener` is called only when the value from the current `watchExpression` and the
-       *   previous call to `watchExpression` are not equal (with the exception of the initial run,
-       *   see below). Inequality is determined according to reference inequality,
-       *   [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators)
-       *    via the `!==` Javascript operator, unless `objectEquality == true`
-       *   (see next point)
-       * - When `objectEquality == true`, inequality of the `watchExpression` is determined
-       *   according to the {@link angular.equals} function. To save the value of the object for
-       *   later comparison, the {@link angular.copy} function is used. This therefore means that
-       *   watching complex objects will have adverse memory and performance implications.
-       * - This should not be used to watch for changes in objects that are
-       *   or contain [File](https://developer.mozilla.org/docs/Web/API/File) objects due to limitations with {@link angular.copy `angular.copy`}.
-       * - The watch `listener` may change the model, which may trigger other `listener`s to fire.
-       *   This is achieved by rerunning the watchers until no changes are detected. The rerun
-       *   iteration limit is 10 to prevent an infinite loop deadlock.
-       *
-       *
-       * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
-       * you can register a `watchExpression` function with no `listener`. (Be prepared for
-       * multiple calls to your `watchExpression` because it will execute multiple times in a
-       * single {@link ng.$rootScope.Scope#$digest $digest} cycle if a change is detected.)
-       *
-       * After a watcher is registered with the scope, the `listener` fn is called asynchronously
-       * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
-       * watcher. In rare cases, this is undesirable because the listener is called when the result
-       * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
-       * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
-       * listener was called due to initialization.
-       *
-       *
-       *
-       * # Example
-       * ```js
-           // let's assume that scope was dependency injected as the $rootScope

-           expect(scope.counter).toEqual(0);

-             function() { return food; },
-             // This is the change listener, called when the value returned from the above function changes
-             function(newValue, oldValue) {

-       * @ngdoc method
-       * @name $rootScope.Scope#$digest
-       * @kind function
-       *
-       * @description
-       * Processes all of the {@link ng.$rootScope.Scope#$watch watchers} of the current scope and
-       * its children. Because a {@link ng.$rootScope.Scope#$watch watcher}'s listener can change
-       * the model, the `$digest()` keeps calling the {@link ng.$rootScope.Scope#$watch watchers}
-       * until no more listeners are firing. This means that it is possible to get into an infinite
-       * loop. This function will throw `'Maximum iteration limit exceeded.'` if the number of
-       * iterations exceeds 10.
-       *
-       * Usually, you don't call `$digest()` directly in
-       * {@link ng.directive:ngController controllers} or in
-       * {@link ng.$compileProvider#directive directives}.
-       * Instead, you should call {@link ng.$rootScope.Scope#$apply $apply()} (typically from within
-       * a {@link ng.$compileProvider#directive directive}), which will force a `$digest()`.
-       *
-       * If you want to be notified whenever `$digest()` is called,
-       * you can register a `watchExpression` function with
-       * {@link ng.$rootScope.Scope#$watch $watch()} with no `listener`.
-       *
-       * In unit tests, you may need to call `$digest()` to simulate the scope life cycle.
-       *
-       * # Example
-       * ```js
-           var scope = ...;
-           scope.name = 'misko';
-           scope.counter = 0;
-
-           expect(scope.counter).toEqual(0);
-           scope.$watch('name', function(newValue, oldValue) {

- * @description
- *
- * `$sceDelegate` is a service that is used by the `$sce` service to provide {@link ng.$sce Strict
- * Contextual Escaping (SCE)} services to AngularJS.
- *
- * Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of
- * the `$sce` service to customize the way Strict Contextual Escaping works in AngularJS.  This is
- * because, while the `$sce` provides numerous shorthand methods, etc., you really only need to
- * override 3 core functions (`trustAs`, `getTrusted` and `valueOf`) to replace the way things
- * work because `$sce` delegates to `$sceDelegate` for these operations.
- *
- * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service.
- *
- * The default instance of `$sceDelegate` should work out of the box with little pain.  While you
- * can override it completely to change the behavior of `$sce`, the common case would
- * involve configuring the {@link ng.$sceDelegateProvider $sceDelegateProvider} instead by setting
- * your own whitelists and blacklists for trusting URLs used for loading AngularJS resources such as
- * templates.  Refer {@link ng.$sceDelegateProvider#resourceUrlWhitelist
- * $sceDelegateProvider.resourceUrlWhitelist} and {@link
- * ng.$sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider.resourceUrlBlacklist}

- * - and you have an open redirect at `http://myapp.example.com/clickThru?...`.

- *  angular.module('myApp', []).config(function($sceDelegateProvider) {
- *    $sceDelegateProvider.resourceUrlWhitelist([
- *      // Allow same origin resource loads.
- *      'self',
- *      // Allow loading from our assets domain.  Notice the difference between * and **.
- *      'http://srv*.assets.example.com/**'

-/**
- * @ngdoc service
- * @name $sce
- * @kind function
- *
- * @description
- *
- * `$sce` is a service that provides Strict Contextual Escaping services to AngularJS.
- *
- * # Strict Contextual Escaping
- *
- * Strict Contextual Escaping (SCE) is a mode in which AngularJS requires bindings in certain
- * contexts to result in a value that is marked as safe to use for that context.  One example of
- * such a context is binding arbitrary html controlled by the user via `ng-bind-html`.  We refer
- * to these contexts as privileged or SCE contexts.
- *
- * As of version 1.2, Angular ships with SCE enabled by default.
- *
- * Note:  When enabled (the default), IE<11 in quirks mode is not supported.  In this mode, IE<11 allow
- * one to execute arbitrary javascript by the use of the expression() syntax.  Refer
- * <http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx> to learn more about them.
- * You can ensure your document is in standards mode and not quirks mode by adding `<!doctype html>`
- * to the top of your HTML document.
- *
- * SCE assists in writing code in a way that (a) is secure by default and (b) makes auditing for
- * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
- *
- * Here's an example of a binding in a privileged context:
- *
- * ```
- * <input ng-model="userHtml" aria-label="User input">
- * <div ng-bind-html="userHtml"></div>
- * ```
- *
- * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user.  With SCE
- * disabled, this application allows the user to render arbitrary HTML into the DIV.
- * In a more realistic example, one may be rendering user comments, blog articles, etc. via
- * bindings.  (HTML is just one example of a context where rendering user controlled input creates
- * security vulnerabilities.)
- *
- * For the case of HTML, you might use a library, either on the client side, or on the server side,
- * to sanitize unsafe HTML before binding to the value and rendering it in the document.
- *
- * How would you ensure that every place that used these types of bindings was bound to a value that
- * was sanitized by your library (or returned as safe for rendering by your server?)  How can you
- * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
- * properties/fields and forgot to update the binding to the sanitized value?
- *
- * To be secure by default, you want to ensure that any such bindings are disallowed unless you can
- * determine that something explicitly says it's safe to use a value for binding in that
- * context.  You can then audit your code (a simple grep would do) to ensure that this is only done
- * for those values that you can easily tell are safe - because they were received from your server,
- * sanitized by your library, etc.  You can organize your codebase to help with this - perhaps
- * allowing only the files in a specific directory to do this.  Ensuring that the internal API
- * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.
- *
- * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
- * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
- * obtain values that will be accepted by SCE / privileged contexts.
- *
- *
- * ## How does it work?
- *
- * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
- * $sce.getTrusted(context, value)} rather than to the value directly.  Directives use {@link
- * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the
- * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals.
- *
- * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
- * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}.  Here's the actual code (slightly
- * simplified):
- *
- * ```
- * var ngBindHtmlDirective = ['$sce', function($sce) {
- *   return function(scope, element, attr) {
- *     scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
- *       element.html(value || '');
- *     });
- *   };
- * }];
- * ```
- *
- * ## Impact on loading templates
- *
- * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
- * `templateUrl`'s specified by {@link guide/directive directives}.
- *
- * By default, Angular only loads templates from the same domain and protocol as the application
- * document.  This is done by calling {@link ng.$sce#getTrustedResourceUrl
- * $sce.getTrustedResourceUrl} on the template URL.  To load templates from other domains and/or
- * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
- * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
- *
- * *Please note*:
- * The browser's
- * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
- * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
- * policy apply in addition to this and may further restrict whether the template is successfully
- * loaded.  This means that without the right CORS policy, loading templates from a different domain
- * won't work on all browsers.  Also, loading templates from `file://` URL does not work on some
- * browsers.
- *
- * ## This feels like too much overhead
- *
- * It's important to remember that SCE only applies to interpolation expressions.
- *
- * If your expressions are constant literals, they're automatically trusted and you don't need to
- * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.
- * `<div ng-bind-html="'<b>implicitly trusted</b>'"></div>`) just works.
- *
- * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them
- * through {@link ng.$sce#getTrusted $sce.getTrusted}.  SCE doesn't play a role here.
- *
- * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
- * templates in `ng-include` from your application's domain without having to even know about SCE.
- * It blocks loading templates from other domains or loading templates over http from an https
- * served document.  You can change these by setting your own custom {@link
- * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link
- * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
- *
- * This significantly reduces the overhead.  It is far easier to pay the small overhead and have an
- * application that's secure and can be audited to verify that with much more ease than bolting
- * security onto an application later.
- *
- * <a name="contexts"></a>
- * ## What trusted context types are supported?
- *
- * | Context             | Notes          |
- * |---------------------|----------------|
- * | `$sce.HTML`         | For HTML that's safe to source into the application.  The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. |
- * | `$sce.CSS`          | For CSS that's safe to source into the application.  Currently unused.  Feel free to use it in your own directives. |
- * | `$sce.URL`          | For URLs that are safe to follow as links.  Currently unused (`<a href=` and `<img src=` sanitize their urls and don't constitute an SCE context. |
- * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application.  Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG`, `VIDEO`, `AUDIO`, `SOURCE`, and `TRACK` (e.g. `IFRAME`, `OBJECT`, etc.)  <br><br>Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. |
- * | `$sce.JS`           | For JavaScript that is safe to execute in your application's context.  Currently unused.  Feel free to use it in your own directives. |
- *
- * ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} <a name="resourceUrlPatternItem"></a>
- *
- *  Each element in these arrays must be one of the following:
- *
- *  - **'self'**
- *    - The special **string**, `'self'`, can be used to match against all URLs of the **same
- *      domain** as the application document using the **same protocol**.
- *  - **String** (except the special value `'self'`)
- *    - The string is matched against the full *normalized / absolute URL* of the resource
- *      being tested (substring matches are not good enough.)
- *    - There are exactly **two wildcard sequences** - `*` and `**`.  All other characters
- *      match themselves.
- *    - `*`: matches zero or more occurrences of any character other than one of the following 6
- *      characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'.  It's a useful wildcard for use
- *      in a whitelist.
- *    - `**`: matches zero or more occurrences of *any* character.  As such, it's not
- *      appropriate for use in a scheme, domain, etc. as it would match too much.  (e.g.
- *      http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
- *      not have been the intention.)  Its usage at the very end of the path is ok.  (e.g.
- *      http://foo.example.com/templates/**).
- *  - **RegExp** (*see caveat below*)
- *    - *Caveat*:  While regular expressions are powerful and offer great flexibility,  their syntax
- *      (and all the inevitable escaping) makes them *harder to maintain*.  It's easy to
- *      accidentally introduce a bug when one updates a complex expression (imho, all regexes should
- *      have good test coverage).  For instance, the use of `.` in the regex is correct only in a
- *      small number of cases.  A `.` character in the regex used when matching the scheme or a
- *      subdomain could be matched against a `:` or literal `.` that was likely not intended.   It
- *      is highly recommended to use the string patterns and only fall back to regular expressions
- *      as a last resort.
- *    - The regular expression must be an instance of RegExp (i.e. not a string.)  It is
- *      matched against the **entire** *normalized / absolute URL* of the resource being tested
- *      (even when the RegExp did not have the `^` and `$` codes.)  In addition, any flags
- *      present on the RegExp (such as multiline, global, ignoreCase) are ignored.
- *    - If you are generating your JavaScript from some other templating engine (not
- *      recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
- *      remember to escape your regular expression (and be aware that you might need more than
- *      one level of escaping depending on your templating engine and the way you interpolated
- *      the value.)  Do make use of your platform's escaping mechanism as it might be good
- *      enough before coding your own.  E.g. Ruby has
- *      [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
- *      and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
- *      Javascript lacks a similar built in function for escaping.  Take a look at Google
- *      Closure library's [goog.string.regExpEscape(s)](
- *      http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).
- *
- * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example.

- * ## Can I disable SCE completely?
- *
- * Yes, you can.  However, this is strongly discouraged.  SCE gives you a lot of security benefits
- * for little coding overhead.  It will be much harder to take an SCE disabled application and
- * either secure it on your own or enable SCE at a later stage.  It might make sense to disable SCE
- * for cases where you have a lot of existing code that was written before SCE was introduced and
- * you're migrating them a module at a time.
- *
- * That said, here's how you can completely disable SCE:
- *
- * ```
- * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
- *   // Completely disable SCE.  For demonstration purposes only!
- *   // Do not use in new projects.
- *   $sceProvider.enabled(false);
- * });
- * ```

-  /* Design notes on the default implementation for SCE.
-   *
-   * The API contract for the SCE delegate
-   * -------------------------------------
-   * The SCE delegate object must provide the following 3 methods:
-   *
-   * - trustAs(contextEnum, value)
-   *     This method is used to tell the SCE service that the provided value is OK to use in the
-   *     contexts specified by contextEnum.  It must return an object that will be accepted by
-   *     getTrusted() for a compatible contextEnum and return this value.
-   *
-   * - valueOf(value)
-   *     For values that were not produced by trustAs(), return them as is.  For values that were
-   *     produced by trustAs(), return the corresponding input value to trustAs.  Basically, if
-   *     trustAs is wrapping the given values into some type, this operation unwraps it when given
-   *     such a value.
-   *
-   * - getTrusted(contextEnum, value)
-   *     This function should return the a value that is safe to use in the context specified by
-   *     contextEnum or throw and exception otherwise.
-   *
-   * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
-   * opaque or wrapped in some holder object.  That happens to be an implementation detail.  For
-   * instance, an implementation could maintain a registry of all trusted objects by context.  In
-   * such a case, trustAs() would return the same object that was passed in.  getTrusted() would
-   * return the same object passed in if it was found in the registry under a compatible context or
-   * throw an exception otherwise.  An implementation might only wrap values some of the time based
-   * on some criteria.  getTrusted() might return a value and not throw an exception for special
-   * constants or objects even if not wrapped.  All such implementations fulfill this contract.
-   *
-   *
-   * A note on the inheritance model for SCE contexts
-   * ------------------------------------------------
-   * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types.  This
-   * is purely an implementation details.
-   *
-   * The contract is simply this:
-   *
-   *     getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
-   *     will also succeed.
-   *
-   * Inheritance happens to capture this in a natural way.  In some future, we
-   * may not use inheritance anymore.  That is OK because no code outside of
-   * sce.js and sceSpecs.js would need to be aware of this detail.

- *
- * Implementation Notes for non-IE browsers
- * ----------------------------------------
- * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
- * results both in the normalizing and parsing of the URL.  Normalizing means that a relative
- * URL will be resolved into an absolute URL in the context of the application document.
- * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
- * properties are all populated to reflect the normalized URL.  This approach has wide
- * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc.  See
- * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
- *
- * Implementation Notes for IE
- * ---------------------------
- * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other
- * browsers.  However, the parsed components will not be set if the URL assigned did not specify
- * them.  (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.)  We
- * work around that by performing the parsing in a 2nd step by taking a previously normalized
- * URL (e.g. by assigning to a.href) and assigning it a.href again.  This correctly populates the
- * properties such as protocol, hostname, port, etc.

- *
- * Filters are just functions which transform input to an output. However filters need to be
- * Dependency Injected. To achieve this a filter definition consists of a factory function which is
- * annotated with dependencies and is responsible for creating a filter function.
- *
- * <div class="alert alert-warning">
- * **Note:** Filter names must be valid angular {@link expression} identifiers, such as `uppercase` or `orderBy`.
- * Names with special characters, such as hyphens and dots, are not allowed. If you wish to namespace
- * your filters, then you can use capitalization (`myappSubsectionFilterx`) or underscores
- * (`myapp_subsection_filterx`).
- * </div>
- *
- * ```js
- *   // Filter registration
- *   function MyModule($provide, $filterProvider) {
- *     // create a service to demonstrate injection (not always needed)
- *     $provide.value('greet', function(name){
- *       return 'Hello ' + name + '!';
- *     });
- *
- *     // register a filter factory which uses the
- *     // greet service to demonstrate DI.
- *     $filterProvider.register('greet', function(greet){
- *       // return the filter function which uses the greet service
- *       // to generate salutation
- *       return function(text) {
- *         // filters need to be forgiving so check input validity
- *         return text && greet(text) || text;
- *       };
- *     });
- *   }
- * ```
- *
- * The filter function is registered with the `$injector` under the filter name suffix with
- * `Filter`.
- *
- * ```js
- *   it('should be the same instance', inject(
- *     function($filterProvider) {
- *       $filterProvider.register('reverse', function(){
- *         return ...;
- *       });
- *     },
- *     function($filter, reverseFilter) {
- *       expect($filter('reverse')).toBe(reverseFilter);
- *     });
- * ```
- *

- * For more information about how angular filters work, and how to create your own filters, see
- * {@link guide/filter Filters} in the Angular Developer Guide.

-/**
- * @ngdoc filter
- * @name filter
- * @kind function
- *
- * @description
- * Selects a subset of items from `array` and returns it as a new array.
- *
- * @param {Array} array The source array.
- * @param {string|Object|function()} expression The predicate to be used for selecting items from
- *   `array`.
- *
- *   Can be one of:
- *
- *   - `string`: The string is used for matching against the contents of the `array`. All strings or
- *     objects with string properties in `array` that match this string will be returned. This also
- *     applies to nested object properties.
- *     The predicate can be negated by prefixing the string with `!`.
- *
- *   - `Object`: A pattern object can be used to filter specific properties on objects contained
- *     by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
- *     which have property `name` containing "M" and property `phone` containing "1". A special
- *     property name (`$` by default) can be used (e.g. as in `{$: "text"}`) to accept a match
- *     against any property of the object or its nested object properties. That's equivalent to the
- *     simple substring match with a `string` as described above. The special property name can be
- *     overwritten, using the `anyPropertyKey` parameter.
- *     The predicate can be negated by prefixing the string with `!`.
- *     For example `{name: "!M"}` predicate will return an array of items which have property `name`
- *     not containing "M".
- *
- *     Note that a named property will match properties on the same level only, while the special
- *     `$` property will match properties on the same level or deeper. E.g. an array item like
- *     `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but
- *     **will** be matched by `{$: 'John'}`.
- *
- *   - `function(value, index, array)`: A predicate function can be used to write arbitrary filters.
- *     The function is called for each element of the array, with the element, its index, and
- *     the entire array itself as arguments.
- *
- *     The final result is an array of those elements that the predicate returned true for.
- *
- * @param {function(actual, expected)|true|false} [comparator] Comparator which is used in
- *     determining if the expected value (from the filter expression) and actual value (from
- *     the object in the array) should be considered a match.
- *
- *   Can be one of:
- *
- *   - `function(actual, expected)`:
- *     The function will be given the object value and the predicate value to compare and
- *     should return true if both values should be considered equal.
- *
- *   - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.
- *     This is essentially strict comparison of expected and actual.
- *
- *   - `false`: A short hand for a function which will look for a substring match in a case
- *     insensitive way. Primitive values are converted to strings. Objects are not compared against
- *     primitives, unless they have a custom `toString` method (e.g. `Date` objects).
- *
- *
- *   Defaults to `false`.
- *
- * @param {string} [anyPropertyKey] The special property name that matches against any property.
- *     By default `$`.
- *
- * @example

- * @ngdoc filter
- * @name date

- *
- * @description
- *   Formats `date` to a string based on the requested `format`.
- *
- *   `format` string can be composed of the following elements:
- *
- *   * `'yyyy'`: 4 digit representation of year (e.g. AD 1 => 0001, AD 2010 => 2010)
- *   * `'yy'`: 2 digit representation of year, padded (00-99). (e.g. AD 2001 => 01, AD 2010 => 10)
- *   * `'y'`: 1 digit representation of year, e.g. (AD 1 => 1, AD 199 => 199)
- *   * `'MMMM'`: Month in year (January-December)
- *   * `'MMM'`: Month in year (Jan-Dec)
- *   * `'MM'`: Month in year, padded (01-12)
- *   * `'M'`: Month in year (1-12)
- *   * `'LLLL'`: Stand-alone month in year (January-December)
- *   * `'dd'`: Day in month, padded (01-31)
- *   * `'d'`: Day in month (1-31)
- *   * `'EEEE'`: Day in Week,(Sunday-Saturday)
- *   * `'EEE'`: Day in Week, (Sun-Sat)
- *   * `'HH'`: Hour in day, padded (00-23)
- *   * `'H'`: Hour in day (0-23)
- *   * `'hh'`: Hour in AM/PM, padded (01-12)
- *   * `'h'`: Hour in AM/PM, (1-12)
- *   * `'mm'`: Minute in hour, padded (00-59)
- *   * `'m'`: Minute in hour (0-59)
- *   * `'ss'`: Second in minute, padded (00-59)
- *   * `'s'`: Second in minute (0-59)
- *   * `'sss'`: Millisecond in second, padded (000-999)
- *   * `'a'`: AM/PM marker
- *   * `'Z'`: 4 digit (+sign) representation of the timezone offset (-1200-+1200)
- *   * `'ww'`: Week of year, padded (00-53). Week 01 is the week with the first Thursday of the year
- *   * `'w'`: Week of year (0-53). Week 1 is the week with the first Thursday of the year
- *   * `'G'`, `'GG'`, `'GGG'`: The abbreviated form of the era string (e.g. 'AD')
- *   * `'GGGG'`: The long form of the era string (e.g. 'Anno Domini')
- *
- *   `format` string can also be one of the following predefined
- *   {@link guide/i18n localizable formats}:
- *
- *   * `'medium'`: equivalent to `'MMM d, y h:mm:ss a'` for en_US locale
- *     (e.g. Sep 3, 2010 12:05:08 PM)
- *   * `'short'`: equivalent to `'M/d/yy h:mm a'` for en_US  locale (e.g. 9/3/10 12:05 PM)
- *   * `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` for en_US  locale
- *     (e.g. Friday, September 3, 2010)
- *   * `'longDate'`: equivalent to `'MMMM d, y'` for en_US  locale (e.g. September 3, 2010)
- *   * `'mediumDate'`: equivalent to `'MMM d, y'` for en_US  locale (e.g. Sep 3, 2010)
- *   * `'shortDate'`: equivalent to `'M/d/yy'` for en_US locale (e.g. 9/3/10)
- *   * `'mediumTime'`: equivalent to `'h:mm:ss a'` for en_US locale (e.g. 12:05:08 PM)
- *   * `'shortTime'`: equivalent to `'h:mm a'` for en_US locale (e.g. 12:05 PM)
- *
- *   `format` string can contain literal values. These need to be escaped by surrounding with single quotes (e.g.
- *   `"h 'in the morning'"`). In order to output a single quote, escape it - i.e., two single quotes in a sequence
- *   (e.g. `"h 'o''clock'"`).
- *
- * @param {(Date|number|string)} date Date to format either as Date object, milliseconds (string or
- *    number) or various ISO 8601 datetime string formats (e.g. yyyy-MM-ddTHH:mm:ss.sssZ and its
- *    shorter versions like yyyy-MM-ddTHH:mmZ, yyyy-MM-dd or yyyyMMddTHHmmssZ). If no timezone is
- *    specified in the string input, the time is considered to be in the local timezone.
- * @param {string=} format Formatting rules (see Description). If not specified,
- *    `mediumDate` is used.
- * @param {string=} timezone Timezone to be used for formatting. It understands UTC/GMT and the
- *    continental US time zone abbreviations, but for general use, use a time zone offset, for
- *    example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
- *    If not specified, the timezone of the browser will be used.
- * @returns {string} Formatted string or the input if input is not recognized as date/millis.

- * @description
- * Creates a new array or string containing only a specified number of elements. The elements are
- * taken from either the beginning or the end of the source array, string or number, as specified by
- * the value and sign (positive or negative) of `limit`. Other array-like objects are also supported

- *
- * @param {Array|ArrayLike|string|number} input - Array/array-like, string or number to be limited.
- * @param {string|number} limit - The length of the returned array or string. If the `limit` number
- *     is positive, `limit` number of items from the beginning of the source array/string are copied.
- *     If the number is negative, `limit` number  of items from the end of the source array/string
- *     are copied. The `limit` will be trimmed if it exceeds `array.length`. If `limit` is undefined,
- *     the input will be returned unchanged.
- * @param {(string|number)=} begin - Index at which to begin limitation. As a negative index,
- *     `begin` indicates an offset from the end of `input`. Defaults to `0`.
- * @returns {Array|string} A new sub-array or substring of length `limit` or less if the input had
- *     less than `limit` elements.

-/**
- * @ngdoc filter
- * @name orderBy
- * @kind function
- *
- * @description
- * Returns an array containing the items from the specified `collection`, ordered by a `comparator`
- * function based on the values computed using the `expression` predicate.
- *
- * For example, `[{id: 'foo'}, {id: 'bar'}] | orderBy:'id'` would result in
- * `[{id: 'bar'}, {id: 'foo'}]`.
- *
- * The `collection` can be an Array or array-like object (e.g. NodeList, jQuery object, TypedArray,
- * String, etc).
- *
- * The `expression` can be a single predicate, or a list of predicates each serving as a tie-breaker
- * for the preceding one. The `expression` is evaluated against each item and the output is used
- * for comparing with other items.
- *
- * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in
- * ascending order.
- *
- * The comparison is done using the `comparator` function. If none is specified, a default, built-in
- * comparator is used (see below for details - in a nutshell, it compares numbers numerically and
- * strings alphabetically).
- *
- * ### Under the hood
- *
- * Ordering the specified `collection` happens in two phases:
- *
- * 1. All items are passed through the predicate (or predicates), and the returned values are saved
- *    along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed
- *    through a predicate that extracts the value of the `label` property, would be transformed to:
- *    ```
- *    {
- *      value: 'foo',
- *      type: 'string',
- *      index: ...
- *    }
- *    ```
- * 2. The comparator function is used to sort the items, based on the derived values, types and
- *    indices.
- *
- * If you use a custom comparator, it will be called with pairs of objects of the form
- * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal
- * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the
- * second, or `1` otherwise.
- *
- * In order to ensure that the sorting will be deterministic across platforms, if none of the
- * specified predicates can distinguish between two items, `orderBy` will automatically introduce a
- * dummy predicate that returns the item's index as `value`.
- * (If you are using a custom comparator, make sure it can handle this predicate as well.)
- *
- * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted
- * value for an item, `orderBy` will try to convert that object to a primitive value, before passing
- * it to the comparator. The following rules govern the conversion:
- *
- * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be
- *    used instead.<br />
- *    (If the object has a `valueOf()` method that returns another object, then the returned object
- *    will be used in subsequent steps.)
- * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that
- *    returns a primitive, its return value will be used instead.<br />
- *    (If the object has a `toString()` method that returns another object, then the returned object
- *    will be used in subsequent steps.)
- * 3. No conversion; the object itself is used.
- *
- * ### The default comparator
- *
- * The default, built-in comparator should be sufficient for most usecases. In short, it compares
- * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to
- * using their index in the original collection, and sorts values of different types by type.
- *
- * More specifically, it follows these steps to determine the relative order of items:
- *
- * 1. If the compared values are of different types, compare the types themselves alphabetically.
- * 2. If both values are of type `string`, compare them alphabetically in a case- and
- *    locale-insensitive way.
- * 3. If both values are objects, compare their indices instead.
- * 4. Otherwise, return:
- *    -  `0`, if the values are equal (by strict equality comparison, i.e. using `===`).
- *    - `-1`, if the 1st value is "less than" the 2nd value (compared using the `<` operator).
- *    -  `1`, otherwise.
- *
- * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being
- *           saved as numbers and not strings.
- * **Note:** For the purpose of sorting, `null` values are treated as the string `'null'` (i.e.
- *           `type: 'string'`, `value: 'null'`). This may cause unexpected sort order relative to
- *           other values.
- *
- * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort.
- * @param {(Function|string|Array.<Function|string>)=} expression - A predicate (or list of
- *    predicates) to be used by the comparator to determine the order of elements.
- *
- *    Can be one of:
- *
- *    - `Function`: A getter function. This function will be called with each item as argument and
- *      the return value will be used for sorting.
- *    - `string`: An Angular expression. This expression will be evaluated against each item and the
- *      result will be used for sorting. For example, use `'label'` to sort by a property called
- *      `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label`
- *      property.<br />
- *      (The result of a constant expression is interpreted as a property name to be used for
- *      comparison. For example, use `'"special name"'` (note the extra pair of quotes) to sort by a
- *      property called `special name`.)<br />
- *      An expression can be optionally prefixed with `+` or `-` to control the sorting direction,
- *      ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided,
- *      (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons.
- *    - `Array`: An array of function and/or string predicates. If a predicate cannot determine the
- *      relative order of two items, the next predicate is used as a tie-breaker.
- *
- * **Note:** If the predicate is missing or empty then it defaults to `'+'`.
- *
- * @param {boolean=} reverse - If `true`, reverse the sorting order.
- * @param {(Function)=} comparator - The comparator function used to determine the relative order of
- *    value pairs. If omitted, the built-in comparator will be used.
- *
- * @returns {Array} - The sorted array.
- *
- *
- * @example
- * ### Ordering a table with `ngRepeat`
- *
- * The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by
- * age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means
- * it defaults to the built-in comparator.

- * ### Using a custom comparator
- *
- * If you have very specific requirements about the way items are sorted, you can pass your own
- * comparator function. For example, you might need to compare some strings in a locale-sensitive
- * way. (When specifying a custom comparator, you also need to pass a value for the `reverse`
- * argument - passing `false` retains the default sorting order, i.e. ascending.)

- * @ngdoc directive
- * @name ngHref
- * @restrict A
- * @priority 99
- *
- * @description
- * Using Angular markup like `{{hash}}` in an href attribute will
- * make the link go to the wrong URL if the user clicks it before
- * Angular has a chance to replace the `{{hash}}` markup with its
- * value. Until Angular replaces the markup the link will be broken
- * and will most likely return a 404 error. The `ngHref` directive
- * solves this problem.
- *
- * The wrong way to write it:
- * ```html
- * <a href="http://www.gravatar.com/avatar/{{hash}}">link1</a>
- * ```
- *
- * The correct way to write it:
- * ```html

- /**
- * @ngdoc directive
- * @name form
- * @restrict E
- *
- * @description
- * Directive that instantiates
- * {@link form.FormController FormController}.
- *
- * If the `name` attribute is specified, the form controller is published onto the current scope under
- * this name.
- *
- * # Alias: {@link ng.directive:ngForm `ngForm`}
- *
- * In Angular, forms can be nested. This means that the outer form is valid when all of the child
- * forms are valid as well. However, browsers do not allow nesting of `<form>` elements, so
- * Angular provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to
- * `form` but can be nested. Nested forms can be useful, for example, if the validity of a sub-group
- * of controls needs to be determined.
- *
- * # CSS classes
- *  - `ng-valid` is set if the form is valid.
- *  - `ng-invalid` is set if the form is invalid.
- *  - `ng-pending` is set if the form is pending.
- *  - `ng-pristine` is set if the form is pristine.
- *  - `ng-dirty` is set if the form is dirty.
- *  - `ng-submitted` is set if the form was submitted.
- *
- * Keep in mind that ngAnimate can detect each of these classes when added and removed.
- *
- *
- * # Submitting a form and preventing the default action
- *
- * Since the role of forms in client-side Angular applications is different than in classical
- * roundtrip apps, it is desirable for the browser not to translate the form submission into a full
- * page reload that sends the data to the server. Instead some javascript logic should be triggered
- * to handle the form submission in an application-specific way.
- *
- * For this reason, Angular prevents the default action (form submission to the server) unless the
- * `<form>` element has an `action` attribute specified.
- *
- * You can use one of the following two ways to specify what javascript method should be called when
- * a form is submitted:
- *
- * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
- * - {@link ng.directive:ngClick ngClick} directive on the first
-  *  button or input field of type submit (input[type=submit])
- *
- * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}
- * or {@link ng.directive:ngClick ngClick} directives.
- * This is because of the following form submission rules in the HTML specification:
- *
- * - If a form has only one input field then hitting enter in this field triggers form submit
- * (`ngSubmit`)
- * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter
- * doesn't trigger submit
- * - if a form has one or more input fields and one or more buttons or input[type=submit] then
- * hitting enter in any of the input fields will trigger the click handler on the *first* button or
- * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
- *
- * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is
- * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
- * to have access to the updated model.
- *
- * ## Animation Hooks
- *
- * Animations in ngForm are triggered when any of the associated CSS classes are added and removed.
- * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any
- * other validations that are performed within the form. Animations in ngForm are similar to how
- * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well
- * as JS animations.
- *
- * The following example shows a simple way to utilize CSS transitions to style a form element
- * that has been rendered as invalid after it has been validated:
- *
- * <pre>
- * //be sure to include ngAnimate as a module to hook into more
- * //advanced animations
- * .my-form {
- *   transition:0.5s linear all;
- *   background: white;
- * }
- * .my-form.ng-invalid {
- *   background: red;
- *   color:white;
- * }
- * </pre>
- *
- * @example
-    <example name="ng-form" deps="angular-animate.js" animations="true" fixBase="true" module="formExample">
-      <file name="index.html">
-       <script>

-       </script>
-       <style>
-        .my-form {
-          transition:all linear 0.5s;
-          background: transparent;
-        }
-        .my-form.ng-invalid {
-          background: red;

-       </style>
-       <form name="myForm" ng-controller="FormController" class="my-form">

-   * @ngdoc input
-   * @name input[text]
-   *
-   * @description
-   * Standard HTML text input with angular data binding, inherited by most of the `input` elements.
-   *
-   *
-   * @param {string} ngModel Assignable angular expression to data-bind to.
-   * @param {string=} name Property name of the form under which the control is published.
-   * @param {string=} required Adds `required` validation error key if the value is not entered.
-   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
-   *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
-   *    `required` when you want to data-bind to the `required` attribute.
-   * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
-   *    minlength.
-   * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
-   *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
-   *    any length.
-   * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
-   *    that contains the regular expression body that will be converted to a regular expression
-   *    as in the ngPattern directive.
-   * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
-   *    does not match a RegExp found by evaluating the Angular expression given in the attribute value.
-   *    If the expression evaluates to a RegExp object, then this is used directly.
-   *    If the expression evaluates to a string, then it will be converted to a RegExp
-   *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
-   *    `new RegExp('^abc$')`.<br />
-   *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
-   *    start at the index of the last search's match, thus not taking the whole input value into
-   *    account.
-   * @param {string=} ngChange Angular expression to be executed when input changes due to user
-   *    interaction with the input element.
-   * @param {boolean=} [ngTrim=true] If set to false Angular will not automatically trim the input.
-   *    This parameter is ignored for input[type=password] controls, which will never trim the
-   *    input.

-   *
-   * <div class="alert alert-warning">
-   * The model must always be of type `number` otherwise Angular will throw an error.

-   * ## Issues with HTML5 constraint validation
-   *
-   * In browsers that follow the
-   * [HTML5 specification](https://html.spec.whatwg.org/multipage/forms.html#number-state-%28type=number%29),
-   * `input[number]` does not work as expected with {@link ngModelOptions `ngModelOptions.allowInvalid`}.
-   * If a non-number is entered in the input, the browser will report the value as an empty string,
-   * which means the view / model values in `ngModel` and subsequently the scope value
-   * will also be an empty string.
-   *
-   *
-   * @param {string} ngModel Assignable angular expression to data-bind to.
-   * @param {string=} name Property name of the form under which the control is published.
-   * @param {string=} min Sets the `min` validation error key if the value entered is less than `min`.
-   *    Can be interpolated.
-   * @param {string=} max Sets the `max` validation error key if the value entered is greater than `max`.
-   *    Can be interpolated.
-   * @param {string=} ngMin Like `min`, sets the `min` validation error key if the value entered is less than `ngMin`,
-   *    but does not trigger HTML5 native validation. Takes an expression.
-   * @param {string=} ngMax Like `max`, sets the `max` validation error key if the value entered is greater than `ngMax`,
-   *    but does not trigger HTML5 native validation. Takes an expression.
-   * @param {string=} step Sets the `step` validation error key if the value entered does not fit the `step` constraint.
-   *    Can be interpolated.
-   * @param {string=} ngStep Like `step`, sets the `step` validation error key if the value entered does not fit the `ngStep` constraint,
-   *    but does not trigger HTML5 native validation. Takes an expression.
-   * @param {string=} required Sets `required` validation error key if the value is not entered.
-   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
-   *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
-   *    `required` when you want to data-bind to the `required` attribute.
-   * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
-   *    minlength.
-   * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
-   *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
-   *    any length.
-   * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
-   *    that contains the regular expression body that will be converted to a regular expression
-   *    as in the ngPattern directive.
-   * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
-   *    does not match a RegExp found by evaluating the Angular expression given in the attribute value.
-   *    If the expression evaluates to a RegExp object, then this is used directly.
-   *    If the expression evaluates to a string, then it will be converted to a RegExp
-   *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
-   *    `new RegExp('^abc$')`.<br />
-   *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
-   *    start at the index of the last search's match, thus not taking the whole input value into
-   *    account.
-   * @param {string=} ngChange Angular expression to be executed when input changes due to user
-   *    interaction with the input element.

-   * @ngdoc input
-   * @name input[range]
-   *
-   * @description
-   * Native range input with validation and transformation.
-   *
-   * The model for the range input must always be a `Number`.
-   *
-   * IE9 and other browsers that do not support the `range` type fall back
-   * to a text input without any default values for `min`, `max` and `step`. Model binding,
-   * validation and number parsing are nevertheless supported.
-   *
-   * Browsers that support range (latest Chrome, Safari, Firefox, Edge) treat `input[range]`
-   * in a way that never allows the input to hold an invalid value. That means:
-   * - any non-numerical value is set to `(max + min) / 2`.
-   * - any numerical value that is less than the current min val, or greater than the current max val
-   * is set to the min / max val respectively.
-   * - additionally, the current `step` is respected, so the nearest value that satisfies a step
-   * is used.
-   *
-   * See the [HTML Spec on input[type=range]](https://www.w3.org/TR/html5/forms.html#range-state-(type=range))
-   * for more info.
-   *
-   * This has the following consequences for Angular:
-   *
-   * Since the element value should always reflect the current model value, a range input
-   * will set the bound ngModel expression to the value that the browser has set for the
-   * input element. For example, in the following input `<input type="range" ng-model="model.value">`,
-   * if the application sets `model.value = null`, the browser will set the input to `'50'`.
-   * Angular will then set the model to `50`, to prevent input and model value being out of sync.
-   *
-   * That means the model for range will immediately be set to `50` after `ngModel` has been
-   * initialized. It also means a range input can never have the required error.
-   *
-   * This does not only affect changes to the model value, but also to the values of the `min`,
-   * `max`, and `step` attributes. When these change in a way that will cause the browser to modify
-   * the input value, Angular will also update the model value.
-   *
-   * Automatic value adjustment also means that a range input element can never have the `required`,
-   * `min`, or `max` errors.
-   *
-   * However, `step` is currently only fully implemented by Firefox. Other browsers have problems
-   * when the step value changes dynamically - they do not adjust the element value correctly, but
-   * instead may set the `stepMismatch` error. If that's the case, the Angular will set the `step`
-   * error on the input, and set the model to `undefined`.
-   *
-   * Note that `input[range]` is not compatible with`ngMax`, `ngMin`, and `ngStep`, because they do
-   * not set the `min` and `max` attributes, which means that the browser won't automatically adjust
-   * the input value based on their values, and will always assume min = 0, max = 100, and step = 1.

-   * @param {string=} min Sets the `min` validation to ensure that the value entered is greater
-   *                  than `min`. Can be interpolated.
-   * @param {string=} max Sets the `max` validation to ensure that the value entered is less than `max`.
-   *                  Can be interpolated.
-   * @param {string=} step Sets the `step` validation to ensure that the value entered matches the `step`

- *    length.
- * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}

- *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to

- *
- * When specifying the `placeholder` attribute of `<textarea>`, Internet Explorer will temporarily
- * insert the placeholder value as the textarea's content. If the placeholder value contains
- * interpolation (`{{ ... }}`), an error will be logged in the console when Angular tries to update
- * the value of the by-then-removed text node. This doesn't affect the functionality of the
- * textarea, but can be undesirable.
- *
- * You can work around this Internet Explorer issue by using `ng-attr-placeholder` instead of
- * `placeholder` on textareas, whenever you need interpolation in the placeholder value. You can
- * find more details on `ngAttr` in the
- * [Interpolation](guide/interpolation#-ngattr-for-binding-to-arbitrary-attributes) section of the

- * @description
- * The `ngBind` attribute tells Angular to replace the text content of the specified HTML element

- *
- * Typically, you don't use `ngBind` directly, but instead you use the double curly markup like

- *
- * It is preferable to use `ngBind` instead of `{{ expression }}` if a template is momentarily
- * displayed by the browser in its raw state before Angular compiles it. Since `ngBind` is an
- * element attribute, it makes the bindings invisible to the user while the page is loading.

- * An alternative solution to this problem would be using the

- * To utilize this functionality, ensure that `$sanitize` is available, for example, by including {@link
- * ngSanitize} in your module's dependencies (not in core Angular). In order to use {@link ngSanitize}
- * in your module's dependencies, you need to include "angular-sanitize.js" in your application.
- *
- * You may also bypass sanitization for values you know are safe. To do so, bind to
- * an explicitly trusted value via {@link ng.$sce#trustAsHtml $sce.trustAsHtml}.  See the example
- * under {@link ng.$sce#show-me-an-example-using-sce- Strict Contextual Escaping (SCE)}.
- *
- * Note: If a `$sanitize` service is unavailable and the bound value isn't explicitly trusted, you
- * will have an exception (instead of an exploit.)
- *
- * @element ANY
- * @param {expression} ngBindHtml {@link guide/expression Expression} to evaluate.

- * Evaluate the given expression when the user changes the input.
- * The expression is evaluated immediately, unlike the JavaScript onchange event
- * which only triggers at the end of a change (usually, when the user leaves the

- *
- * The `ngChange` expression is only evaluated when a change in the input value causes
- * a new value to be committed to the model.
- *
- * It will not be evaluated:
- * * if the value returned from the `$parsers` transformation pipeline has not changed
- * * if the input has continued to be invalid since the model will stay `null`
- * * if the model is changed programmatically and not by a change to the input value

-/**
- * @ngdoc directive
- * @name ngClass
- * @restrict AC
- *
- * @description
- * The `ngClass` directive allows you to dynamically set CSS classes on an HTML element by databinding
- * an expression that represents all classes to be added.
- *
- * The directive operates in three different ways, depending on which of three types the expression
- * evaluates to:
- *
- * 1. If the expression evaluates to a string, the string should be one or more space-delimited class
- * names.
- *
- * 2. If the expression evaluates to an object, then for each key-value pair of the
- * object with a truthy value the corresponding key is used as a class name.
- *
- * 3. If the expression evaluates to an array, each element of the array should either be a string as in
- * type 1 or an object as in type 2. This means that you can mix strings and objects together in an array
- * to give you more control over what CSS classes appear. See the code below for an example of this.
- *
- *
- * The directive won't add duplicate classes if a particular class was already set.
- *
- * When the expression changes, the previously added classes are removed and only then are the
- * new classes added.
- *
- * @knownIssue
- * You should not use {@link guide/interpolation interpolation} in the value of the `class`
- * attribute, when using the `ngClass` directive on the same element.
- * See {@link guide/interpolation#known-issues here} for more info.
- *
- * @animations
- * | Animation                        | Occurs                              |
- * |----------------------------------|-------------------------------------|
- * | {@link ng.$animate#addClass addClass}       | just before the class is applied to the element   |
- * | {@link ng.$animate#removeClass removeClass} | just before the class is removed from the element |
- *
- * @element ANY
- * @param {expression} ngClass {@link guide/expression Expression} to eval. The result
- *   of the evaluation can be a string representing space delimited class
- *   names, an array, or a map of class names to boolean values. In the case of a map, the
- *   names of the properties whose values are truthy will be added as css classes to the
- *   element.
- *

-     <file name="style.css">

-         transition:all cubic-bezier(0.250, 0.460, 0.450, 0.940) 0.5s;
-       }
-
-       .base-class.my-class {
-         color: red;
-         font-size:3em;
-       }
-     </file>
-     <file name="protractor.js" type="protractor">
-       it('should check ng-class', function() {
-         expect(element(by.css('.base-class')).getAttribute('class')).not.
-           toMatch(/my-class/);
-
-         element(by.id('setbtn')).click();
-
-         expect(element(by.css('.base-class')).getAttribute('class')).
-           toMatch(/my-class/);
-
-         element(by.id('clearbtn')).click();
-
-         expect(element(by.css('.base-class')).getAttribute('class')).not.
-           toMatch(/my-class/);
-       });
-     </file>
-   </example>
-
-
-   ## ngClass and pre-existing CSS3 Transitions/Animations
-   The ngClass directive still supports CSS3 Transitions/Animations even if they do not follow the ngAnimate CSS naming structure.
-   Upon animation ngAnimate will apply supplementary CSS classes to track the start and end of an animation, but this will not hinder
-   any pre-existing CSS transitions already on the element. To get an idea of what happens during a class-based animation, be sure
-   to view the step by step details of {@link $animate#addClass $animate.addClass} and
-   {@link $animate#removeClass $animate.removeClass}.

-/**
- * @ngdoc directive
- * @name ngCloak
- * @restrict AC
- *
- * @description
- * The `ngCloak` directive is used to prevent the Angular html template from being briefly
- * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
- * directive to avoid the undesirable flicker effect caused by the html template display.
- *
- * The directive can be applied to the `<body>` element, but the preferred usage is to apply
- * multiple `ngCloak` directives to small portions of the page to permit progressive rendering
- * of the browser view.
- *
- * `ngCloak` works in cooperation with the following css rule embedded within `angular.js` and
- * `angular.min.js`.
- * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
- *
- * ```css
- * [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
- *   display: none !important;
- * }
- * ```
- *
- * When this css rule is loaded by the browser, all html elements (including their children) that
- * are tagged with the `ngCloak` directive are hidden. When Angular encounters this directive
- * during the compilation of the template it deletes the `ngCloak` element attribute, making
- * the compiled element visible.
- *
- * For the best result, the `angular.js` script must be loaded in the head section of the html
- * document; alternatively, the css rule above must be included in the external stylesheet of the
- * application.
- *
- * @element ANY
- *
- * @example
-   <example name="ng-cloak">
-     <file name="index.html">
-        <div id="template1" ng-cloak>{{ 'hello' }}</div>
-        <div id="template2" class="ng-cloak">{{ 'world' }}</div>

-/**
- * @ngdoc directive
- * @name ngController
- *
- * @description
- * The `ngController` directive attaches a controller class to the view. This is a key aspect of how angular
- * supports the principles behind the Model-View-Controller design pattern.
- *
- * MVC components in angular:
- *
- * * Model — Models are the properties of a scope; scopes are attached to the DOM where scope properties
- *   are accessed through bindings.
- * * View — The template (HTML with data bindings) that is rendered into the View.
- * * Controller — The `ngController` directive specifies a Controller class; the class contains business
- *   logic behind the application to decorate the scope with functions and values
- *
- * Note that you can also attach controllers to the DOM by declaring it in a route definition
- * via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller
- * again using `ng-controller` in the template itself.  This will cause the controller to be attached
- * and executed twice.
- *
- * @element ANY
- * @scope
- * @priority 500
- * @param {expression} ngController Name of a constructor function registered with the current
- * {@link ng.$controllerProvider $controllerProvider} or an {@link guide/expression expression}
- * that on the current scope evaluates to a constructor function.
- *
- * The controller instance can be published into a scope property by specifying
- * `ng-controller="as propertyName"`.
- *
- * If the current `$controllerProvider` is configured to use globals (via
- * {@link ng.$controllerProvider#allowGlobals `$controllerProvider.allowGlobals()` }), this may
- * also be the name of a globally accessible constructor function (deprecated, not recommended).
- *
- * @example
- * Here is a simple form for editing user contact information. Adding, removing, clearing, and
- * greeting are methods declared on the controller (see source tab). These methods can
- * easily be called from the angular markup. Any changes to the data are automatically reflected
- * in the View without the need for a manual update.
- *
- * Two different declaration styles are included below:
- *
- * * one binds methods and properties directly onto the controller using `this`:
- * `ng-controller="SettingsController1 as settings"`
- * * one injects `$scope` into the controller:
- * `ng-controller="SettingsController2"`
- *
- * The second option is more common in the Angular community, and is generally used in boilerplates
- * and in this guide. However, there are advantages to binding properties directly to the controller
- * and avoiding scope.
- *
- * * Using `controller as` makes it obvious which controller you are accessing in the template when
- * multiple controllers apply to an element.
- * * If you are writing your controllers as classes you have easier access to the properties and
- * methods, which will appear on the scope, from inside the controller code.
- * * Since there is always a `.` in the bindings, you don't have to worry about prototypal
- * inheritance masking primitives.
- *
- * This example demonstrates the `controller as` syntax.
- *
- * <example name="ngControllerAs" module="controllerAsExample">
- *   <file name="index.html">
- *    <div id="ctrl-as-exmpl" ng-controller="SettingsController1 as settings">

-/**
- * @ngdoc directive
- * @name ngCsp
- *
- * @restrict A
- * @element ANY
- * @description
- *
- * Angular has some features that can conflict with certain restrictions that are applied when using
- * [CSP (Content Security Policy)](https://developer.mozilla.org/en/Security/CSP) rules.
- *
- * If you intend to implement CSP with these rules then you must tell Angular not to use these
- * features.
- *
- * This is necessary when developing things like Google Chrome Extensions or Universal Windows Apps.
- *
- *
- * The following default rules in CSP affect Angular:
- *
- * * The use of `eval()`, `Function(string)` and similar functions to dynamically create and execute
- * code from strings is forbidden. Angular makes use of this in the {@link $parse} service to
- * provide a 30% increase in the speed of evaluating Angular expressions. (This CSP rule can be
- * disabled with the CSP keyword `unsafe-eval`, but it is generally not recommended as it would
- * weaken the protections offered by CSP.)
- *
- * * The use of inline resources, such as inline `<script>` and `<style>` elements, are forbidden.
- * This prevents apps from injecting custom styles directly into the document. Angular makes use of
- * this to include some CSS rules (e.g. {@link ngCloak} and {@link ngHide}). To make these
- * directives work when a CSP rule is blocking inline styles, you must link to the `angular-csp.css`
- * in your HTML manually. (This CSP rule can be disabled with the CSP keyword `unsafe-inline`, but
- * it is generally not recommended as it would weaken the protections offered by CSP.)
- *
- * If you do not provide `ngCsp` then Angular tries to autodetect if CSP is blocking dynamic code
- * creation from strings (e.g., `unsafe-eval` not specified in CSP header) and automatically
- * deactivates this feature in the {@link $parse} service. This autodetection, however, triggers a
- * CSP error to be logged in the console:
- *
- * ```
- * Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of
- * script in the following Content Security Policy directive: "default-src 'self'". Note that
- * 'script-src' was not explicitly set, so 'default-src' is used as a fallback.
- * ```
- *
- * This error is harmless but annoying. To prevent the error from showing up, put the `ngCsp`
- * directive on an element of the HTML document that appears before the `<script>` tag that loads
- * the `angular.js` file.
- *
- * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.*
- *
- * You can specify which of the CSP related Angular features should be deactivated by providing
- * a value for the `ng-csp` attribute. The options are as follows:
- *
- * * no-inline-style: this stops Angular from injecting CSS styles into the DOM
- *
- * * no-unsafe-eval: this stops Angular from optimizing $parse with unsafe eval of strings
- *
- * You can use these values in the following combinations:
- *
- *
- * * No declaration means that Angular will assume that you can do inline styles, but it will do
- * a runtime check for unsafe-eval. E.g. `<body>`. This is backwardly compatible with previous
- * versions of Angular.
- *
- * * A simple `ng-csp` (or `data-ng-csp`) attribute will tell Angular to deactivate both inline
- * styles and unsafe eval. E.g. `<body ng-csp>`. This is backwardly compatible with previous
- * versions of Angular.
- *
- * * Specifying only `no-unsafe-eval` tells Angular that we must not use eval, but that we can
- * inject inline styles. E.g. `<body ng-csp="no-unsafe-eval">`.
- *
- * * Specifying only `no-inline-style` tells Angular that we must not inject styles, but that we can
- * run eval - no automatic check for unsafe eval will occur. E.g. `<body ng-csp="no-inline-style">`
- *
- * * Specifying both `no-unsafe-eval` and `no-inline-style` tells Angular that we must not inject
- * styles nor use eval, which is the same as an empty: ng-csp.
- * E.g.`<body ng-csp="no-inline-style;no-unsafe-eval">`
- *
- * @example
- * This example shows how to apply the `ngCsp` directive to the `html` tag.
-   ```html
-     <!doctype html>
-     <html ng-app ng-csp>
-     ...
-     ...
-     </html>

-/**
- * @ngdoc directive
- * @name ngIf
- * @restrict A
- * @multiElement
- *
- * @description
- * The `ngIf` directive removes or recreates a portion of the DOM tree based on an
- * {expression}. If the expression assigned to `ngIf` evaluates to a false
- * value then the element is removed from the DOM, otherwise a clone of the
- * element is reinserted into the DOM.
- *
- * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the
- * element in the DOM rather than changing its visibility via the `display` css property.  A common
- * case when this difference is significant is when using css selectors that rely on an element's
- * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.
- *
- * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope
- * is created when the element is restored.  The scope created within `ngIf` inherits from
- * its parent scope using
- * [prototypal inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance).
- * An important implication of this is if `ngModel` is used within `ngIf` to bind to
- * a javascript primitive defined in the parent scope. In this case any modifications made to the
- * variable within the child scope will override (hide) the value in the parent scope.
- *
- * Also, `ngIf` recreates elements using their compiled state. An example of this behavior
- * is if an element's class attribute is directly modified after it's compiled, using something like
- * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element
- * the added class will be lost because the original compiled state is used to regenerate the element.
- *
- * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter`
- * and `leave` effects.
- *
- * @animations
- * | Animation                        | Occurs                               |
- * |----------------------------------|-------------------------------------|
- * | {@link ng.$animate#enter enter}  | just after the `ngIf` contents change and a new DOM element is created and injected into the `ngIf` container |
- * | {@link ng.$animate#leave leave}  | just before the `ngIf` contents are removed from the DOM |
- *
- * @element ANY
- * @scope
- * @priority 600
- * @param {expression} ngIf If the {@link guide/expression expression} is falsy then
- *     the element is removed from the DOM tree. If it is truthy a copy of the compiled
- *     element is added to the DOM tree.
- *

-/**
- * @ngdoc directive
- * @name ngInclude
- * @restrict ECA
- *
- * @description
- * Fetches, compiles and includes an external HTML fragment.
- *
- * By default, the template URL is restricted to the same domain and protocol as the
- * application document. This is done by calling {@link $sce#getTrustedResourceUrl
- * $sce.getTrustedResourceUrl} on it. To load templates from other domains or protocols
- * you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist them} or
- * {@link $sce#trustAsResourceUrl wrap them} as trusted values. Refer to Angular's {@link
- * ng.$sce Strict Contextual Escaping}.
- *
- * In addition, the browser's
- * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
- * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
- * policy may further restrict whether the template is successfully loaded.
- * For example, `ngInclude` won't work for cross-domain requests on all browsers and for `file://`
- * access on some browsers.
- *
- * @animations
- * | Animation                        | Occurs                              |
- * |----------------------------------|-------------------------------------|
- * | {@link ng.$animate#enter enter}  | when the expression changes, on the new include |
- * | {@link ng.$animate#leave leave}  | when the expression changes, on the old include |
- *
- * The enter and leave animation occur concurrently.
- *
- * @scope
- * @priority 400
- *
- * @param {string} ngInclude|src angular expression evaluating to URL. If the source is a string constant,
- *                 make sure you wrap it in **single** quotes, e.g. `src="'myPartialTemplate.html'"`.
- * @param {string=} onload Expression to evaluate when a new partial is loaded.
- *                  <div class="alert alert-warning">
- *                  **Note:** When using onload on SVG elements in IE11, the browser will try to call
- *                  a function with the name on the window element, which will usually throw a
- *                  "function is undefined" error. To fix this, you can instead use `data-onload` or a
- *                  different form that {@link guide/directive#normalization matches} `onload`.
- *                  </div>
-   *
- * @param {string=} autoscroll Whether `ngInclude` should call {@link ng.$anchorScroll
- *                  $anchorScroll} to scroll the viewport after the content is loaded.
- *
- *                  - If the attribute is not set, disable scrolling.
- *                  - If the attribute is set without value, enable scrolling.
- *                  - Otherwise enable scrolling only if the expression evaluates to truthy value.

- * This directive can be abused to add unnecessary amounts of logic into your templates.
- * There are only a few appropriate uses of `ngInit`, such as for aliasing special properties of

- * server side scripting. Besides these few cases, you should use {@link guide/controller controllers}
- * rather than `ngInit` to initialize values on a scope.
- * </div>
- *
- * <div class="alert alert-warning">
- * **Note**: If you have assignment in `ngInit` along with a {@link ng.$filter `filter`}, make
- * sure you have parentheses to ensure correct operator precedence:
- * <pre class="prettyprint">
- * `<div ng-init="test1 = ($index | toString)"></div>`

-/**
- * @ngdoc directive
- * @name ngList
- *
- * @description
- * Text input that converts between a delimited string and an array of strings. The default
- * delimiter is a comma followed by a space - equivalent to `ng-list=", "`. You can specify a custom
- * delimiter as the value of the `ngList` attribute - for example, `ng-list=" | "`.
- *
- * The behaviour of the directive is affected by the use of the `ngTrim` attribute.
- * * If `ngTrim` is set to `"false"` then whitespace around both the separator and each
- *   list item is respected. This implies that the user of the directive is responsible for
- *   dealing with whitespace but also allows you to use whitespace as a delimiter, such as a
- *   tab or newline character.
- * * Otherwise whitespace around the delimiter is ignored when splitting (although it is respected
- *   when joining the list items back together) and whitespace around each list item is stripped
- *   before it is added to the model.

- * @property {*} $viewValue The actual value from the control's view. For `input` elements, this is a
- * String. See {@link ngModel.NgModelController#$setViewValue} for information about when the $viewValue
- * is set.
- * @property {*} $modelValue The value in the model that the control is bound to.
- * @property {Array.<Function>} $parsers Array of functions to execute, as a pipeline, whenever
-       the control reads value from the DOM. The functions are called in array order, each passing
-       its return value through to the next. The last return value is forwarded to the
-       {@link ngModel.NgModelController#$validators `$validators`} collection.
-
-Parsers are used to sanitize / convert the {@link ngModel.NgModelController#$viewValue
-`$viewValue`}.
-
-Returning `undefined` from a parser means a parse error occurred. In that case,
-no {@link ngModel.NgModelController#$validators `$validators`} will run and the `ngModel`
-will be set to `undefined` unless {@link ngModelOptions `ngModelOptions.allowInvalid`}
-is set to `true`. The parse error is stored in `ngModel.$error.parse`.
-
- *
- * @property {Array.<Function>} $formatters Array of functions to execute, as a pipeline, whenever
-       the model value changes. The functions are called in reverse array order, each passing the value through to the
-       next. The last return value is used as the actual DOM value.
-       Used to format / convert values for display in the control.
- * ```js
- * function formatter(value) {
- *   if (value) {
- *     return value.toUpperCase();
- *   }
- * }
- * ngModel.$formatters.push(formatter);
- * ```
- *
- * @property {Object.<string, function>} $validators A collection of validators that are applied
- *      whenever the model value changes. The key value within the object refers to the name of the
- *      validator while the function refers to the validation operation. The validation operation is
- *      provided with the model value as an argument and must return a true or false value depending
- *      on the response of that validation.
- *
- * ```js
- * ngModel.$validators.validCharacters = function(modelValue, viewValue) {
- *   var value = modelValue || viewValue;
- *   return /[0-9]+/.test(value) &&
- *          /[a-z]+/.test(value) &&
- *          /[A-Z]+/.test(value) &&
- *          /\W+/.test(value);
- * };
- * ```
- *
- * @property {Object.<string, function>} $asyncValidators A collection of validations that are expected to
- *      perform an asynchronous validation (e.g. a HTTP request). The validation function that is provided
- *      is expected to return a promise when it is run during the model validation process. Once the promise
- *      is delivered then the validation status will be set to true when fulfilled and false when rejected.
- *      When the asynchronous validators are triggered, each of the validators will run in parallel and the model
- *      value will only be updated once all validators have been fulfilled. As long as an asynchronous validator
- *      is unfulfilled, its key will be added to the controllers `$pending` property. Also, all asynchronous validators
- *      will only run once all synchronous validators have passed.
- *
- * Please note that if $http is used then it is important that the server returns a success HTTP response code
- * in order to fulfill the validation and a status level of `4xx` in order to reject the validation.
- *
- * ```js
- * ngModel.$asyncValidators.uniqueUsername = function(modelValue, viewValue) {
- *   var value = modelValue || viewValue;
- *
- *   // Lookup user by username
- *   return $http.get('/api/users/' + value).
- *      then(function resolved() {
- *        //username exists, this means validation fails
- *        return $q.reject('exists');
- *      }, function rejected() {
- *        //username does not exist, therefore this validation passes
- *        return true;
- *      });
- * };
- * ```
- *
- * @property {Array.<Function>} $viewChangeListeners Array of functions to execute whenever the
- *     view value has changed. It is called with no arguments, and its return value is ignored.
- *     This can be used in place of additional $watches against the model value.
- *
- * @property {Object} $error An object hash with all failing validator ids as keys.
- * @property {Object} $pending An object hash with all pending validator ids as keys.
- *
- * @property {boolean} $untouched True if control has not lost focus yet.
- * @property {boolean} $touched True if control has lost focus.
- * @property {boolean} $pristine True if user has not interacted with the control yet.
- * @property {boolean} $dirty True if user has already interacted with the control.
- * @property {boolean} $valid True if there is no error.
- * @property {boolean} $invalid True if at least one error on the control.
- * @property {string} $name The name attribute of the control.
- *
- * @description
- *
- * `NgModelController` provides API for the {@link ngModel `ngModel`} directive.
- * The controller contains services for data-binding, validation, CSS updates, and value formatting
- * and parsing. It purposefully does not contain any logic which deals with DOM rendering or
- * listening to DOM events.
- * Such DOM related logic should be provided by other directives which make use of
- * `NgModelController` for data-binding to control elements.
- * Angular provides this DOM logic for most {@link input `input`} elements.
- * At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example
- * custom control example} that uses `ngModelController` to bind to `contenteditable` elements.
- *
- * @example
- * ### Custom Control Example
- * This example shows how to use `NgModelController` with a custom control to achieve
- * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
- * collaborate together to achieve the desired result.
- *
- * `contenteditable` is an HTML5 attribute, which tells the browser to let the element
- * contents be edited in place by the user.
- *
- * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
- * module to automatically remove "bad" content like inline event listener (e.g. `<span onclick="...">`).
- * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks
- * that content using the `$sce` service.
- *
- * <example name="NgModelController" module="customControl" deps="angular-sanitize.js">
-    <file name="style.css">
-      [contenteditable] {
-        border: 1px solid black;

-      }

-   *
-   * @description
-   * Update the view value.
-   *
-   * This method should be called when a control wants to change the view value; typically,
-   * this is done from within a DOM event handler. For example, the {@link ng.directive:input input}
-   * directive calls it when the value of the input changes and {@link ng.directive:select select}
-   * calls it when an option is selected.
-   *
-   * When `$setViewValue` is called, the new `value` will be staged for committing through the `$parsers`
-   * and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged
-   * value sent directly for processing, finally to be applied to `$modelValue` and then the
-   * **expression** specified in the `ng-model` attribute. Lastly, all the registered change listeners,
-   * in the `$viewChangeListeners` list, are called.
-   *
-   * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`
-   * and the `default` trigger is not listed, all those actions will remain pending until one of the
-   * `updateOn` events is triggered on the DOM element.
-   * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}
-   * directive is used with a custom debounce for this particular event.
-   * Note that a `$digest` is only triggered once the `updateOn` events are fired, or if `debounce`
-   * is specified, once the timer runs out.
-   *
-   * When used with standard inputs, the view value will always be a string (which is in some cases
-   * parsed into another type, such as a `Date` object for `input[date]`.)
-   * However, custom controls might also pass objects to this method. In this case, we should make
-   * a copy of the object before passing it to `$setViewValue`. This is because `ngModel` does not
-   * perform a deep watch of objects, it only looks for a change of identity. If you only change
-   * the property of the object then ngModel will not realize that the object has changed and
-   * will not invoke the `$parsers` and `$validators` pipelines. For this reason, you should
-   * not change properties of the copy once it has been passed to `$setViewValue`.
-   * Otherwise you may cause the model value on the scope to change incorrectly.
-   *
-   * <div class="alert alert-info">
-   * In any case, the value passed to the method should always reflect the current value
-   * of the control. For example, if you are calling `$setViewValue` for an input element,
-   * you should pass the input DOM value. Otherwise, the control and the scope model become
-   * out of sync. It's also important to note that `$setViewValue` does not call `$render` or change
-   * the control's DOM value in any way. If we want to change the control's DOM value
-   * programmatically, we should update the `ngModel` scope expression. Its new value will be
-   * picked up by the model controller, which will run it through the `$formatters`, `$render` it
-   * to update the DOM, and finally call `$validate` on it.

- * @ngdoc directive
- * @name ngModel
- *
- * @element input
- * @priority 1
- *
- * @description
- * The `ngModel` directive binds an `input`,`select`, `textarea` (or custom form control) to a
- * property on the scope using {@link ngModel.NgModelController NgModelController},
- * which is created and exposed by this directive.
- *
- * `ngModel` is responsible for:
- *
- * - Binding the view into the model, which other directives such as `input`, `textarea` or `select`
- *   require.
- * - Providing validation behavior (i.e. required, number, email, url).
- * - Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
- * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`,
- *   `ng-untouched`, `ng-empty`, `ng-not-empty`) including animations.
- * - Registering the control with its parent {@link ng.directive:form form}.
- *
- * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
- * current scope. If the property doesn't already exist on this scope, it will be created
- * implicitly and added to the scope.
- *
- * For best practices on using `ngModel`, see:
- *
- *  - [Understanding Scopes](https://github.com/angular/angular.js/wiki/Understanding-Scopes)
- *
- * For basic examples, how to use `ngModel`, see:
- *
- *  - {@link ng.directive:input input}
- *    - {@link input[text] text}
- *    - {@link input[checkbox] checkbox}
- *    - {@link input[radio] radio}
- *    - {@link input[number] number}
- *    - {@link input[email] email}
- *    - {@link input[url] url}
- *    - {@link input[date] date}
- *    - {@link input[datetime-local] datetime-local}
- *    - {@link input[time] time}
- *    - {@link input[month] month}
- *    - {@link input[week] week}
- *  - {@link ng.directive:select select}
- *  - {@link ng.directive:textarea textarea}
- *
- * # Complex Models (objects or collections)
- *
- * By default, `ngModel` watches the model by reference, not value. This is important to know when
- * binding inputs to models that are objects (e.g. `Date`) or collections (e.g. arrays). If only properties of the
- * object or collection change, `ngModel` will not be notified and so the input will not be  re-rendered.
- *
- * The model must be assigned an entirely new object or collection before a re-rendering will occur.
- *
- * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression
- * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or
- * if the select is given the `multiple` attribute.
- *
- * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the
- * first level of the object (or only changing the properties of an item in the collection if it's an array) will still
- * not trigger a re-rendering of the model.
- *
- * # CSS classes
- * The following CSS classes are added and removed on the associated input/select/textarea element
- * depending on the validity of the model.
- *
- *  - `ng-valid`: the model is valid
- *  - `ng-invalid`: the model is invalid
- *  - `ng-valid-[key]`: for each valid key added by `$setValidity`
- *  - `ng-invalid-[key]`: for each invalid key added by `$setValidity`
- *  - `ng-pristine`: the control hasn't been interacted with yet
- *  - `ng-dirty`: the control has been interacted with
- *  - `ng-touched`: the control has been blurred
- *  - `ng-untouched`: the control hasn't been blurred
- *  - `ng-pending`: any `$asyncValidators` are unfulfilled
- *  - `ng-empty`: the view does not contain a value or the value is deemed "empty", as defined
- *     by the {@link ngModel.NgModelController#$isEmpty} method
- *  - `ng-not-empty`: the view contains a non-empty value
- *
- * Keep in mind that ngAnimate can detect each of these classes when added and removed.
- *
- * ## Animation Hooks
- *
- * Animations within models are triggered when any of the associated CSS classes are added and removed
- * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`,
- * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
- * The animations that are triggered within ngModel are similar to how they work in ngClass and
- * animations can be hooked into using CSS transitions, keyframes as well as JS animations.
- *
- * The following example shows a simple way to utilize CSS transitions to style an input element
- * that has been rendered as invalid after it has been validated:
- *
- * <pre>
- * //be sure to include ngAnimate as a module to hook into more
- * //advanced animations
- * .my-input {
- *   transition:0.5s linear all;
- *   background: white;
- * }
- * .my-input.ng-invalid {
- *   background: red;
- *   color:white;
- * }
- * </pre>
- *
- * @example
- * <example deps="angular-animate.js" animations="true" fixBase="true" module="inputExample" name="ng-model">
-     <file name="index.html">
-       <script>
-        angular.module('inputExample', [])
-          .controller('ExampleController', ['$scope', function($scope) {
-            $scope.val = '1';
-          }]);

- * ## Binding to a getter/setter
- *
- * Sometimes it's helpful to bind `ngModel` to a getter/setter function.  A getter/setter is a
- * function that returns a representation of the model when called with zero arguments, and sets
- * the internal state of a model when called with an argument. It's sometimes useful to use this
- * for models that have an internal representation that's different from what the model exposes
- * to the view.
- *
- * <div class="alert alert-success">
- * **Best Practice:** It's best to keep getters fast because Angular is likely to call them more
- * frequently than other parts of your code.
- * </div>
- *
- * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that
- * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to
- * a `<form>`, which will enable this behavior for all `<input>`s within it. See
- * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.
- *
- * The following example shows how to use `ngModel` with a getter/setter:
- *
- * @example
- * <example name="ngModel-getter-setter" module="getterSetterExample">
-     <file name="index.html">
-       <div ng-controller="ExampleController">
-         <form name="userForm">
-           <label>Name:
-             <input type="text" name="userName"
-                    ng-model="user.name"
-                    ng-model-options="{ getterSetter: true }" />
-           </label>
-         </form>
-         <pre>user.name = <span ng-bind="user.name()"></span></pre>
-       </div>
-     </file>
-     <file name="app.js">
-       angular.module('getterSetterExample', [])
-         .controller('ExampleController', ['$scope', function($scope) {
-           var _name = 'Brian';
-           $scope.user = {
-             name: function(newName) {
-              // Note that newName can be undefined for two reasons:
-              // 1. Because it is called as a getter and thus called with no arguments
-              // 2. Because the property should actually be set to undefined. This happens e.g. if the
-              //    input is invalid
-              return arguments.length ? (_name = newName) : _name;
-             }
-           };
-         }]);

-/**
- * @ngdoc directive
- * @name ngModelOptions
- *
- * @description
- * This directive allows you to modify the behaviour of {@link ngModel} directives within your
- * application. You can specify an `ngModelOptions` directive on any element. All {@link ngModel}
- * directives will use the options of their nearest `ngModelOptions` ancestor.
- *
- * The `ngModelOptions` settings are found by evaluating the value of the attribute directive as
- * an Angular expression. This expression should evaluate to an object, whose properties contain
- * the settings. For example: `<div "ng-model-options"="{ debounce: 100 }"`.
- *
- * ## Inheriting Options
- *
- * You can specify that an `ngModelOptions` setting should be inherited from a parent `ngModelOptions`
- * directive by giving it the value of `"$inherit"`.
- * Then it will inherit that setting from the first `ngModelOptions` directive found by traversing up the
- * DOM tree. If there is no ancestor element containing an `ngModelOptions` directive then default settings
- * will be used.
- *
- * For example given the following fragment of HTML
- *
- *
- * ```html
- * <div ng-model-options="{ allowInvalid: true, debounce: 200 }">
- *   <form ng-model-options="{ updateOn: 'blur', allowInvalid: '$inherit' }">
- *     <input ng-model-options="{ updateOn: 'default', allowInvalid: '$inherit' }" />
- *   </form>
- * </div>
- * ```
- *
- * the `input` element will have the following settings
- *
- * ```js
- * { allowInvalid: true, updateOn: 'default', debounce: 0 }
- * ```
- *
- * Notice that the `debounce` setting was not inherited and used the default value instead.
- *
- * You can specify that all undefined settings are automatically inherited from an ancestor by
- * including a property with key of `"*"` and value of `"$inherit"`.
- *
- * For example given the following fragment of HTML
- *
- *
- * ```html
- * <div ng-model-options="{ allowInvalid: true, debounce: 200 }">
- *   <form ng-model-options="{ updateOn: 'blur', "*": '$inherit' }">
- *     <input ng-model-options="{ updateOn: 'default', "*": '$inherit' }" />
- *   </form>
- * </div>
- * ```
- *
- * the `input` element will have the following settings
- *
- * ```js
- * { allowInvalid: true, updateOn: 'default', debounce: 200 }
- * ```
- *
- * Notice that the `debounce` setting now inherits the value from the outer `<div>` element.
- *
- * If you are creating a reusable component then you should be careful when using `"*": "$inherit"`
- * since you may inadvertently inherit a setting in the future that changes the behavior of your component.
- *
- *
- * ## Triggering and debouncing model updates
- *
- * The `updateOn` and `debounce` properties allow you to specify a custom list of events that will
- * trigger a model update and/or a debouncing delay so that the actual update only takes place when
- * a timer expires; this timer will be reset after another change takes place.
- *
- * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might
- * be different from the value in the actual model. This means that if you update the model you
- * should also invoke {@link ngModel.NgModelController#$rollbackViewValue} on the relevant input field in
- * order to make sure it is synchronized with the model and that any debounced action is canceled.
- *
- * The easiest way to reference the control's {@link ngModel.NgModelController#$rollbackViewValue}
- * method is by making sure the input is placed inside a form that has a `name` attribute. This is
- * important because `form` controllers are published to the related scope under the name in their
- * `name` attribute.
- *
- * Any pending changes will take place immediately when an enclosing form is submitted via the
- * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
- * to have access to the updated model.
- *
- * The following example shows how to override immediate updates. Changes on the inputs within the
- * form will update the model only when the control loses focus (blur event). If `escape` key is
- * pressed while the input field is focused, the value is reset to the value in the current model.
- *
- * <example name="ngModelOptions-directive-blur" module="optionsExample">
- *   <file name="index.html">
- *     <div ng-controller="ExampleController">
- *       <form name="userForm">
- *         <label>
- *           Name:
- *           <input type="text" name="userName"
- *                  ng-model="user.name"
- *                  ng-model-options="{ updateOn: 'blur' }"
- *                  ng-keyup="cancel($event)" />
- *         </label><br />

- *           Other data:
- *           <input type="text" ng-model="user.data" />
- *         </label><br />
- *       </form>
- *       <pre>user.name = <span ng-bind="user.name"></span></pre>

- *       .controller('ExampleController', ['$scope', function($scope) {
- *         $scope.user = { name: 'say', data: '' };
- *
- *         $scope.cancel = function(e) {
- *           if (e.keyCode === 27) {
- *             $scope.userForm.userName.$rollbackViewValue();
- *           }
- *         };
- *       }]);
- *   </file>
- *   <file name="protractor.js" type="protractor">
- *     var model = element(by.binding('user.name'));
- *     var input = element(by.model('user.name'));
- *     var other = element(by.model('user.data'));
- *
- *     it('should allow custom events', function() {
- *       input.sendKeys(' hello');
- *       input.click();
- *       expect(model.getText()).toEqual('say');
- *       other.click();
- *       expect(model.getText()).toEqual('say hello');
- *     });
- *
- *     it('should $rollbackViewValue when model changes', function() {
- *       input.sendKeys(' hello');
- *       expect(input.getAttribute('value')).toEqual('say hello');
- *       input.sendKeys(protractor.Key.ESCAPE);
- *       expect(input.getAttribute('value')).toEqual('say');
- *       other.click();
- *       expect(model.getText()).toEqual('say');
- *     });
- *   </file>
- * </example>
- *
- * The next example shows how to debounce model changes. Model will be updated only 1 sec after last change.
- * If the `Clear` button is pressed, any debounced action is canceled and the value becomes empty.
- *
- * <example name="ngModelOptions-directive-debounce" module="optionsExample">
- *   <file name="index.html">
- *     <div ng-controller="ExampleController">
- *       <form name="userForm">
- *         Name:
- *         <input type="text" name="userName"
- *                ng-model="user.name"
- *                ng-model-options="{ debounce: 1000 }" />
- *         <button ng-click="userForm.userName.$rollbackViewValue(); user.name=''">Clear</button><br />
- *       </form>
- *       <pre>user.name = <span ng-bind="user.name"></span></pre>
- *     </div>
- *   </file>
- *   <file name="app.js">
- *     angular.module('optionsExample', [])
- *       .controller('ExampleController', ['$scope', function($scope) {
- *         $scope.user = { name: 'say' };
- *       }]);
- *   </file>
- * </example>
- *
- * ## Model updates and validation
- *
- * The default behaviour in `ngModel` is that the model value is set to `undefined` when the
- * validation determines that the value is invalid. By setting the `allowInvalid` property to true,
- * the model will still be updated even if the value is invalid.
- *
- *
- * ## Connecting to the scope
- *
- * By setting the `getterSetter` property to true you are telling ngModel that the `ngModel` expression
- * on the scope refers to a "getter/setter" function rather than the value itself.
- *
- * The following example shows how to bind to getter/setters:
- *
- * <example name="ngModelOptions-directive-getter-setter" module="getterSetterExample">
- *   <file name="index.html">
- *     <div ng-controller="ExampleController">
- *       <form name="userForm">
- *         <label>
- *           Name:
- *           <input type="text" name="userName"
- *                  ng-model="user.name"
- *                  ng-model-options="{ getterSetter: true }" />
- *         </label>
- *       </form>
- *       <pre>user.name = <span ng-bind="user.name()"></span></pre>
- *     </div>
- *   </file>
- *   <file name="app.js">
- *     angular.module('getterSetterExample', [])
- *       .controller('ExampleController', ['$scope', function($scope) {
- *         var _name = 'Brian';
- *         $scope.user = {
- *           name: function(newName) {
- *             return angular.isDefined(newName) ? (_name = newName) : _name;
- *           }
- *         };
- *       }]);
- *   </file>
- * </example>
- *
- *
- * ## Specifying timezones
- *
- * You can specify the timezone that date/time input directives expect by providing its name in the
- * `timezone` property.
- *
- * @param {Object} ngModelOptions options to apply to {@link ngModel} directives on this element and
- *   and its descendents. Valid keys are:
- *   - `updateOn`: string specifying which event should the input be bound to. You can set several
- *     events using an space delimited list. There is a special event called `default` that
- *     matches the default events belonging to the control.
- *   - `debounce`: integer value which contains the debounce model update value in milliseconds. A
- *     value of 0 triggers an immediate update. If an object is supplied instead, you can specify a
- *     custom value for each event. For example:
- *     ```
- *     ng-model-options="{
- *       updateOn: 'default blur',
- *       debounce: { 'default': 500, 'blur': 0 }
- *     }"
- *     ```
- *   - `allowInvalid`: boolean value which indicates that the model can be set with values that did
- *     not validate correctly instead of the default behavior of setting the model to undefined.
- *   - `getterSetter`: boolean value which determines whether or not to treat functions bound to
- *     `ngModel` as getters/setters.
- *   - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for
- *     `<input type="date" />`, `<input type="time" />`, ... . It understands UTC/GMT and the
- *     continental US time zone abbreviations, but for general use, use a time zone offset, for
- *     example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
- *     If not specified, the timezone of the browser will be used.

- * In many cases, {@link ng.directive:ngRepeat ngRepeat} can be used on `<option>` elements instead of
- * `ngOptions` to achieve a similar result. However, `ngOptions` provides some benefits:
- * - more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the
- * comprehension expression
- * - reduced memory consumption by not creating a new scope for each repeated instance
- * - increased render speed by creating the options in a documentFragment instead of individually
- *
- * When an item in the `<select>` menu is selected, the array element or object property
- * represented by the selected option will be bound to the model identified by the `ngModel`
- * directive.
- *
- * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
- * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
- * option. See example below for demonstration.
- *
- * ## Complex Models (objects or collections)
- *
- * By default, `ngModel` watches the model by reference, not value. This is important to know when
- * binding the select to a model that is an object or a collection.
- *
- * One issue occurs if you want to preselect an option. For example, if you set
- * the model to an object that is equal to an object in your collection, `ngOptions` won't be able to set the selection,
- * because the objects are not identical. So by default, you should always reference the item in your collection
- * for preselections, e.g.: `$scope.selected = $scope.collection[3]`.
- *
- * Another solution is to use a `track by` clause, because then `ngOptions` will track the identity
- * of the item not by reference, but by the result of the `track by` expression. For example, if your
- * collection items have an id property, you would `track by item.id`.
- *
- * A different issue with objects or collections is that ngModel won't detect if an object property or
- * a collection item changes. For that reason, `ngOptions` additionally watches the model using
- * `$watchCollection`, when the expression contains a `track by` clause or the the select has the `multiple` attribute.
- * This allows ngOptions to trigger a re-rendering of the options even if the actual object/collection
- * has not changed identity, but only a property on the object or an item in the collection changes.
- *
- * Note that `$watchCollection` does a shallow comparison of the properties of the object (or the items in the collection
- * if the model is an array). This means that changing a property deeper than the first level inside the
- * object/collection will not trigger a re-rendering.
- *
- * ## `select` **`as`**
- *
- * Using `select` **`as`** will bind the result of the `select` expression to the model, but
- * the value of the `<select>` and `<option>` html elements will be either the index (for array data sources)
- * or property name (for object data sources) of the value within the collection. If a **`track by`** expression
- * is used, the result of that expression will be set as the value of the `option` and `select` elements.
- *
- *
- * ### `select` **`as`** and **`track by`**
- *
- * <div class="alert alert-warning">
- * Be careful when using `select` **`as`** and **`track by`** in the same expression.
- * </div>
- *
- * Given this array of items on the $scope:
- *
- * ```js
- * $scope.items = [{
- *   id: 1,
- *   label: 'aLabel',
- *   subItem: { name: 'aSubItem' }
- * }, {
- *   id: 2,
- *   label: 'bLabel',
- *   subItem: { name: 'bSubItem' }
- * }];
- * ```
- *
- * This will work:
- *
- * ```html
- * <select ng-options="item as item.label for item in items track by item.id" ng-model="selected"></select>
- * ```
- * ```js
- * $scope.selected = $scope.items[0];
- * ```
- *
- * but this will not work:
- *
- * ```html
- * <select ng-options="item.subItem as item.label for item in items track by item.id" ng-model="selected"></select>
- * ```
- * ```js
- * $scope.selected = $scope.items[0].subItem;
- * ```
- *
- * In both examples, the **`track by`** expression is applied successfully to each `item` in the
- * `items` array. Because the selected option has been set programmatically in the controller, the
- * **`track by`** expression is also applied to the `ngModel` value. In the first example, the
- * `ngModel` value is `items[0]` and the **`track by`** expression evaluates to `items[0].id` with
- * no issue. In the second example, the `ngModel` value is `items[0].subItem` and the **`track by`**
- * expression evaluates to `items[0].subItem.id` (which is undefined). As a result, the model value
- * is not matched against any `<option>` and the `<select>` appears as having no selected value.
- *
- *
- * @param {string} ngModel Assignable angular expression to data-bind to.
- * @param {string=} name Property name of the form under which the control is published.
- * @param {string=} required The control is considered valid only if value is entered.
- * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
- *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
- *    `required` when you want to data-bind to the `required` attribute.
- * @param {comprehension_expression=} ngOptions in one of the following forms:
- *
- *   * for array data sources:
- *     * `label` **`for`** `value` **`in`** `array`
- *     * `select` **`as`** `label` **`for`** `value` **`in`** `array`
- *     * `label` **`group by`** `group` **`for`** `value` **`in`** `array`
- *     * `label` **`disable when`** `disable` **`for`** `value` **`in`** `array`
- *     * `label` **`group by`** `group` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`
- *     * `label` **`disable when`** `disable` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`
- *     * `label` **`for`** `value` **`in`** `array` | orderBy:`orderexpr` **`track by`** `trackexpr`
- *        (for including a filter with `track by`)
- *   * for object data sources:
- *     * `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
- *     * `select` **`as`** `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
- *     * `label` **`group by`** `group` **`for (`**`key`**`,`** `value`**`) in`** `object`
- *     * `label` **`disable when`** `disable` **`for (`**`key`**`,`** `value`**`) in`** `object`
- *     * `select` **`as`** `label` **`group by`** `group`
- *         **`for` `(`**`key`**`,`** `value`**`) in`** `object`
- *     * `select` **`as`** `label` **`disable when`** `disable`
- *         **`for` `(`**`key`**`,`** `value`**`) in`** `object`
- *
- * Where:
- *
- *   * `array` / `object`: an expression which evaluates to an array / object to iterate over.
- *   * `value`: local variable which will refer to each item in the `array` or each property value
- *      of `object` during iteration.
- *   * `key`: local variable which will refer to a property name in `object` during iteration.
- *   * `label`: The result of this expression will be the label for `<option>` element. The
- *     `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).
- *   * `select`: The result of this expression will be bound to the model of the parent `<select>`
- *      element. If not specified, `select` expression will default to `value`.
- *   * `group`: The result of this expression will be used to group options using the `<optgroup>`
- *      DOM element.
- *   * `disable`: The result of this expression will be used to disable the rendered `<option>`
- *      element. Return `true` to disable.
- *   * `trackexpr`: Used when working with an array of objects. The result of this expression will be
- *      used to identify the objects in the array. The `trackexpr` will most likely refer to the
- *     `value` variable (e.g. `value.propertyName`). With this the selection is preserved
- *      even when the options are recreated (e.g. reloaded from the server).

-/**
- * @ngdoc directive
- * @name ngPluralize
- * @restrict EA
- *
- * @description
- * `ngPluralize` is a directive that displays messages according to en-US localization rules.
- * These rules are bundled with angular.js, but can be overridden
- * (see {@link guide/i18n Angular i18n} dev guide). You configure ngPluralize directive
- * by specifying the mappings between
- * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
- * and the strings to be displayed.
- *
- * # Plural categories and explicit number rules
- * There are two
- * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
- * in Angular's default en-US locale: "one" and "other".
- *
- * While a plural category may match many numbers (for example, in en-US locale, "other" can match
- * any number that is not 1), an explicit number rule can only match one number. For example, the
- * explicit number rule for "3" matches the number 3. There are examples of plural categories
- * and explicit number rules throughout the rest of this documentation.
- *
- * # Configuring ngPluralize
- * You configure ngPluralize by providing 2 attributes: `count` and `when`.
- * You can also provide an optional attribute, `offset`.
- *
- * The value of the `count` attribute can be either a string or an {@link guide/expression
- * Angular expression}; these are evaluated on the current scope for its bound value.
- *
- * The `when` attribute specifies the mappings between plural categories and the actual
- * string to be displayed. The value of the attribute should be a JSON object.
- *
- * The following example shows how to configure ngPluralize:
- *
- * ```html
- * <ng-pluralize count="personCount"
-                 when="{'0': 'Nobody is viewing.',
- *                      'one': '1 person is viewing.',
- *                      'other': '{} people are viewing.'}">
- * </ng-pluralize>
- *```
- *
- * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
- * specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
- * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
- * other numbers, for example 12, so that instead of showing "12 people are viewing", you can
- * show "a dozen people are viewing".
- *
- * You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted
- * into pluralized strings. In the previous example, Angular will replace `{}` with
- * <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder
- * for <span ng-non-bindable>{{numberExpression}}</span>.
- *
- * If no rule is defined for a category, then an empty string is displayed and a warning is generated.
- * Note that some locales define more categories than `one` and `other`. For example, fr-fr defines `few` and `many`.
- *
- * # Configuring ngPluralize with offset
- * The `offset` attribute allows further customization of pluralized text, which can result in
- * a better user experience. For example, instead of the message "4 people are viewing this document",
- * you might display "John, Kate and 2 others are viewing this document".
- * The offset attribute allows you to offset a number by any desired value.
- * Let's take a look at an example:
- *
- * ```html
- * <ng-pluralize count="personCount" offset=2
- *               when="{'0': 'Nobody is viewing.',
- *                      '1': '{{person1}} is viewing.',
- *                      '2': '{{person1}} and {{person2}} are viewing.',
- *                      'one': '{{person1}}, {{person2}} and one other person are viewing.',
- *                      'other': '{{person1}}, {{person2}} and {} other people are viewing.'}">
- * </ng-pluralize>
- * ```
- *
- * Notice that we are still using two plural categories(one, other), but we added
- * three explicit number rules 0, 1 and 2.
- * When one person, perhaps John, views the document, "John is viewing" will be shown.
- * When three people view the document, no explicit number rule is found, so
- * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.
- * In this case, plural category 'one' is matched and "John, Mary and one other person are viewing"
- * is shown.
- *
- * Note that when you specify offsets, you must provide explicit number rules for
- * numbers from 0 up to and including the offset. If you use an offset of 3, for example,
- * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
- * plural categories "one" and "other".
- *
- * @param {string|expression} count The variable to be bound to.
- * @param {string} when The mapping between plural category to its corresponding strings.
- * @param {number=} offset Offset to deduct from the total number.
- *

-/**
- * @ngdoc directive
- * @name ngRepeat
- * @multiElement
- *
- * @description
- * The `ngRepeat` directive instantiates a template once per item from a collection. Each template
- * instance gets its own scope, where the given loop variable is set to the current collection item,
- * and `$index` is set to the item index or key.
- *
- * Special properties are exposed on the local scope of each template instance, including:
- *
- * | Variable  | Type            | Details                                                                     |
- * |-----------|-----------------|-----------------------------------------------------------------------------|
- * | `$index`  | {@type number}  | iterator offset of the repeated element (0..length-1)                       |
- * | `$first`  | {@type boolean} | true if the repeated element is first in the iterator.                      |
- * | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. |
- * | `$last`   | {@type boolean} | true if the repeated element is last in the iterator.                       |
- * | `$even`   | {@type boolean} | true if the iterator position `$index` is even (otherwise false).           |
- * | `$odd`    | {@type boolean} | true if the iterator position `$index` is odd (otherwise false).            |
- *
- * <div class="alert alert-info">
- *   Creating aliases for these properties is possible with {@link ng.directive:ngInit `ngInit`}.
- *   This may be useful when, for instance, nesting ngRepeats.
- * </div>
- *
- *
- * # Iterating over object properties
- *
- * It is possible to get `ngRepeat` to iterate over the properties of an object using the following
- * syntax:
- *
- * ```js
- * <div ng-repeat="(key, value) in myObj"> ... </div>
- * ```
- *
- * However, there are a few limitations compared to array iteration:
- *
- * - The JavaScript specification does not define the order of keys
- *   returned for an object, so Angular relies on the order returned by the browser
- *   when running `for key in myObj`. Browsers generally follow the strategy of providing
- *   keys in the order in which they were defined, although there are exceptions when keys are deleted
- *   and reinstated. See the
- *   [MDN page on `delete` for more info](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete#Cross-browser_notes).
- *
- * - `ngRepeat` will silently *ignore* object keys starting with `$`, because
- *   it's a prefix used by Angular for public (`$`) and private (`$$`) properties.
- *
- * - The built-in filters {@link ng.orderBy orderBy} and {@link ng.filter filter} do not work with
- *   objects, and will throw an error if used with one.
- *
- * If you are hitting any of these limitations, the recommended workaround is to convert your object into an array
- * that is sorted into the order that you prefer before providing it to `ngRepeat`. You could
- * do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter)
- * or implement a `$watch` on the object yourself.
- *
- *
- * # Tracking and Duplicates
- *
- * `ngRepeat` uses {@link $rootScope.Scope#$watchCollection $watchCollection} to detect changes in
- * the collection. When a change happens, `ngRepeat` then makes the corresponding changes to the DOM:
- *
- * * When an item is added, a new instance of the template is added to the DOM.
- * * When an item is removed, its template instance is removed from the DOM.
- * * When items are reordered, their respective templates are reordered in the DOM.
- *
- * To minimize creation of DOM elements, `ngRepeat` uses a function
- * to "keep track" of all items in the collection and their corresponding DOM elements.
- * For example, if an item is added to the collection, `ngRepeat` will know that all other items
- * already have DOM elements, and will not re-render them.
- *
- * The default tracking function (which tracks items by their identity) does not allow
- * duplicate items in arrays. This is because when there are duplicates, it is not possible
- * to maintain a one-to-one mapping between collection items and DOM elements.
- *
- * If you do need to repeat duplicate items, you can substitute the default tracking behavior
- * with your own using the `track by` expression.
- *
- * For example, you may track items by the index of each item in the collection, using the
- * special scope property `$index`:
- * ```html
- *    <div ng-repeat="n in [42, 42, 43, 43] track by $index">
- *      {{n}}
- *    </div>
- * ```
- *
- * You may also use arbitrary expressions in `track by`, including references to custom functions
- * on the scope:
- * ```html
- *    <div ng-repeat="n in [42, 42, 43, 43] track by myTrackingFunction(n)">
- *      {{n}}
- *    </div>
- * ```
- *
- * <div class="alert alert-success">
- * If you are working with objects that have a unique identifier property, you should track
- * by this identifier instead of the object instance. Should you reload your data later, `ngRepeat`
- * will not have to rebuild the DOM elements for items it has already rendered, even if the
- * JavaScript objects in the collection have been substituted for new ones. For large collections,
- * this significantly improves rendering performance. If you don't have a unique identifier,
- * `track by $index` can also provide a performance boost.
- * </div>
- *
- * ```html
- *    <div ng-repeat="model in collection track by model.id">
- *      {{model.name}}
- *    </div>
- * ```
- *
- * <br />
- * <div class="alert alert-warning">
- * Avoid using `track by $index` when the repeated template contains
- * {@link guide/expression#one-time-binding one-time bindings}. In such cases, the `nth` DOM
- * element will always be matched with the `nth` item of the array, so the bindings on that element
- * will not be updated even when the corresponding item changes, essentially causing the view to get
- * out-of-sync with the underlying data.
- * </div>
- *
- * When no `track by` expression is provided, it is equivalent to tracking by the built-in
- * `$id` function, which tracks items by their identity:
- * ```html
- *    <div ng-repeat="obj in collection track by $id(obj)">
- *      {{obj.prop}}
- *    </div>
- * ```
- *
- * <br />
- * <div class="alert alert-warning">
- * **Note:** `track by` must always be the last expression:
- * </div>
- * ```
- *    <div ng-repeat="model in collection | orderBy: 'id' as filtered_result track by model.id">
- *      {{model.name}}
- *    </div>
- * ```
- *
- *
- * # Special repeat start and end points
- * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending
- * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.
- * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)
- * up to and including the ending HTML tag where **ng-repeat-end** is placed.
- *
- * The example below makes use of this feature:
- * ```html
- *   <header ng-repeat-start="item in items">
- *     Header {{ item }}
- *   </header>
- *   <div class="body">
- *     Body {{ item }}
- *   </div>
- *   <footer ng-repeat-end>
- *     Footer {{ item }}
- *   </footer>
- * ```
- *
- * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:
- * ```html
- *   <header>
- *     Header A
- *   </header>
- *   <div class="body">
- *     Body A
- *   </div>
- *   <footer>
- *     Footer A
- *   </footer>
- *   <header>
- *     Header B
- *   </header>
- *   <div class="body">
- *     Body B
- *   </div>
- *   <footer>
- *     Footer B
- *   </footer>
- * ```
- *
- * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such
- * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).
- *
- * @animations
- * | Animation                        | Occurs                              |
- * |----------------------------------|-------------------------------------|
- * | {@link ng.$animate#enter enter} | when a new item is added to the list or when an item is revealed after a filter |
- * | {@link ng.$animate#leave leave} | when an item is removed from the list or when an item is filtered out |
- * | {@link ng.$animate#move move } | when an adjacent item is filtered out causing a reorder or when the item contents are reordered |
- *
- * See the example below for defining CSS animations with ngRepeat.
- *
- * @element ANY
- * @scope
- * @priority 1000
- * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These
- *   formats are currently supported:
- *
- *   * `variable in expression` – where variable is the user defined loop variable and `expression`
- *     is a scope expression giving the collection to enumerate.
- *
- *     For example: `album in artist.albums`.
- *
- *   * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
- *     and `expression` is the scope expression giving the collection to enumerate.
- *
- *     For example: `(name, age) in {'adam':10, 'amalie':12}`.
- *
- *   * `variable in expression track by tracking_expression` – You can also provide an optional tracking expression
- *     which can be used to associate the objects in the collection with the DOM elements. If no tracking expression
- *     is specified, ng-repeat associates elements by identity. It is an error to have
- *     more than one tracking expression value resolve to the same key. (This would mean that two distinct objects are
- *     mapped to the same DOM element, which is not possible.)
- *
- *     Note that the tracking expression must come last, after any filters, and the alias expression.
- *
- *     For example: `item in items` is equivalent to `item in items track by $id(item)`. This implies that the DOM elements
- *     will be associated by item identity in the array.
- *
- *     For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique
- *     `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements
- *     with the corresponding item in the array by identity. Moving the same object in array would move the DOM
- *     element in the same way in the DOM.
- *
- *     For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this
- *     case the object identity does not matter. Two objects are considered equivalent as long as their `id`
- *     property is same.
- *
- *     For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter
- *     to items in conjunction with a tracking expression.
- *
- *   * `variable in expression as alias_expression` – You can also provide an optional alias expression which will then store the
- *     intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message
- *     when a filter is active on the repeater, but the filtered result set is empty.
- *
- *     For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after
- *     the items have been processed through the filter.
- *
- *     Please note that `as [variable name] is not an operator but rather a part of ngRepeat micro-syntax so it can be used only at the end
- *     (and not as operator, inside an expression).
- *
- *     For example: `item in items | filter : x | orderBy : order | limitTo : limit as results` .
- *
- * @example
- * This example uses `ngRepeat` to display a list of people. A filter is used to restrict the displayed
- * results by name or by age. New (entering) and removed (leaving) items are animated.

-/**
- * @ngdoc directive
- * @name ngShow
- * @multiElement
- *
- * @description
- * The `ngShow` directive shows or hides the given HTML element based on the expression
- * provided to the `ngShow` attribute. The element is shown or hidden by removing or adding
- * the `.ng-hide` CSS class onto the element. The `.ng-hide` CSS class is predefined
- * in AngularJS and sets the display style to none (using an !important flag).
- * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
- *
- * ```html
- * <!-- when $scope.myValue is truthy (element is visible) -->
- * <div ng-show="myValue"></div>
- *
- * <!-- when $scope.myValue is falsy (element is hidden) -->
- * <div ng-show="myValue" class="ng-hide"></div>
- * ```
- *
- * When the `ngShow` expression evaluates to a falsy value then the `.ng-hide` CSS class is added to the class
- * attribute on the element causing it to become hidden. When truthy, the `.ng-hide` CSS class is removed
- * from the element causing the element not to appear hidden.
- *
- * ## Why is !important used?
- *
- * You may be wondering why !important is used for the `.ng-hide` CSS class. This is because the `.ng-hide` selector
- * can be easily overridden by heavier selectors. For example, something as simple
- * as changing the display style on a HTML list item would make hidden elements appear visible.
- * This also becomes a bigger issue when dealing with CSS frameworks.
- *
- * By using !important, the show and hide behavior will work as expected despite any clash between CSS selector
- * specificity (when !important isn't used with any conflicting styles). If a developer chooses to override the
- * styling to change how to hide an element then it is just a matter of using !important in their own CSS code.
- *
- * ### Overriding `.ng-hide`
- *
- * By default, the `.ng-hide` class will style the element with `display: none!important`. If you wish to change
- * the hide behavior with ngShow/ngHide then this can be achieved by restating the styles for the `.ng-hide`
- * class CSS. Note that the selector that needs to be used is actually `.ng-hide:not(.ng-hide-animate)` to cope
- * with extra animation classes that can be added.
- *
- * ```css
- * .ng-hide:not(.ng-hide-animate) {
- *   /&#42; this is just another form of hiding an element &#42;/
- *   display: block!important;
- *   position: absolute;
- *   top: -9999px;
- *   left: -9999px;
- * }
- * ```
- *
- * By default you don't need to override in CSS anything and the animations will work around the display style.
- *
- * ## A note about animations with `ngShow`
- *
- * Animations in ngShow/ngHide work with the show and hide events that are triggered when the directive expression
- * is true and false. This system works like the animation system present with ngClass except that
- * you must also include the !important flag to override the display property
- * so that you can perform an animation when the element is hidden during the time of the animation.
- *
- * ```css
- * //
- * //a working example can be found at the bottom of this page
- * //
- * .my-element.ng-hide-add, .my-element.ng-hide-remove {
- *   /&#42; this is required as of 1.3x to properly
- *      apply all styling in a show/hide animation &#42;/
- *   transition: 0s linear all;
- * }
- *
- * .my-element.ng-hide-add-active,
- * .my-element.ng-hide-remove-active {
- *   /&#42; the transition is defined in the active class &#42;/
- *   transition: 1s linear all;
- * }
- *
- * .my-element.ng-hide-add { ... }
- * .my-element.ng-hide-add.ng-hide-add-active { ... }
- * .my-element.ng-hide-remove { ... }
- * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
- * ```
- *
- * Keep in mind that, as of AngularJS version 1.3, there is no need to change the display
- * property to block during animation states--ngAnimate will handle the style toggling automatically for you.
- *
- * @animations
- * | Animation                        | Occurs                              |

- * | {@link $animate#addClass addClass} `.ng-hide`  | after the `ngShow` expression evaluates to a non truthy value and just before the contents are set to hidden |

- * The `ngStyle` directive allows you to set CSS style on an HTML element conditionally.
- *
- * @knownIssue
- * You should not use {@link guide/interpolation interpolation} in the value of the `style`
- * attribute, when using the `ngStyle` directive on the same element.
- * See {@link guide/interpolation#known-issues here} for more info.
- *
- * @element ANY
- * @param {expression} ngStyle
- *
- * {@link guide/expression Expression} which evals to an
- * object whose keys are CSS style names and values are corresponding values for those CSS
- * keys.
- *
- * Since some CSS style names are not valid keys for an object, they must be quoted.
- * See the 'background-color' style in the example below.
- *
- * @example
-   <example name="ng-style">
-     <file name="index.html">
-        <input type="button" value="set color" ng-click="myStyle={color:'red'}">
-        <input type="button" value="set background" ng-click="myStyle={'background-color':'blue'}">
-        <input type="button" value="clear" ng-click="myStyle={}">
-        <br/>

-/**
- * @ngdoc directive
- * @name ngSwitch
- * @restrict EA
- *
- * @description
- * The `ngSwitch` directive is used to conditionally swap DOM structure on your template based on a scope expression.
- * Elements within `ngSwitch` but without `ngSwitchWhen` or `ngSwitchDefault` directives will be preserved at the location
- * as specified in the template.
- *
- * The directive itself works similar to ngInclude, however, instead of downloading template code (or loading it
- * from the template cache), `ngSwitch` simply chooses one of the nested elements and makes it visible based on which element
- * matches the value obtained from the evaluated expression. In other words, you define a container element
- * (where you place the directive), place an expression on the **`on="..."` attribute**
- * (or the **`ng-switch="..."` attribute**), define any inner elements inside of the directive and place
- * a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on
- * expression is evaluated. If a matching expression is not found via a when attribute then an element with the default
- * attribute is displayed.
- *
- * <div class="alert alert-info">
- * Be aware that the attribute values to match against cannot be expressions. They are interpreted
- * as literal string values to match against.
- * For example, **`ng-switch-when="someVal"`** will match against the string `"someVal"` not against the
- * value of the expression `$scope.someVal`.
- * </div>
-
- * @animations
- * | Animation                        | Occurs                              |
- * |----------------------------------|-------------------------------------|
- * | {@link ng.$animate#enter enter}  | after the ngSwitch contents change and the matched child element is placed inside the container |
- * | {@link ng.$animate#leave leave}  | after the ngSwitch contents change and just before the former contents are removed from the DOM |
- *
- * @usage
- *
- * ```
- * <ANY ng-switch="expression">
- *   <ANY ng-switch-when="matchValue1">...</ANY>
- *   <ANY ng-switch-when="matchValue2">...</ANY>
- *   <ANY ng-switch-default>...</ANY>
- * </ANY>
- * ```
- *
- *
- * @scope
- * @priority 1200
- * @param {*} ngSwitch|on expression to match against <code>ng-switch-when</code>.
- * On child elements add:
- *
- * * `ngSwitchWhen`: the case statement to match against. If match then this
- *   case will be displayed. If the same match appears multiple times, all the
- *   elements will be displayed. It is possible to associate multiple values to
- *   the same `ngSwitchWhen` by defining the optional attribute
- *   `ngSwitchWhenSeparator`. The separator will be used to split the value of
- *   the `ngSwitchWhen` attribute into multiple tokens, and the element will show
- *   if any of the `ngSwitch` evaluates to any of these tokens.
- * * `ngSwitchDefault`: the default case when no other case match. If there
- *   are multiple default cases, all of them will be displayed when no other
- *   case match.
- *

-/**
- * @ngdoc directive
- * @name ngTransclude
- * @restrict EAC
- *
- * @description
- * Directive that marks the insertion point for the transcluded DOM of the nearest parent directive that uses transclusion.
- *
- * You can specify that you want to insert a named transclusion slot, instead of the default slot, by providing the slot name
- * as the value of the `ng-transclude` or `ng-transclude-slot` attribute.
- *
- * If the transcluded content is not empty (i.e. contains one or more DOM nodes, including whitespace text nodes), any existing
- * content of this element will be removed before the transcluded content is inserted.
- * If the transcluded content is empty (or only whitespace), the existing content is left intact. This lets you provide fallback
- * content in the case that no transcluded content is provided.
- *
- * @element ANY
- *
- * @param {string} ngTransclude|ngTranscludeSlot the name of the slot to insert at this point. If this is not provided, is empty
- *                                               or its value is the same as the name of the attribute then the default slot is used.
- *
- * @example
- * ### Basic transclusion
- * This example demonstrates basic transclusion of content into a component directive.
- * <example name="simpleTranscludeExample" module="transcludeExample">
- *   <file name="index.html">
- *     <script>
- *       angular.module('transcludeExample', [])
- *        .directive('pane', function(){

- *             restrict: 'E',
- *             transclude: true,
- *             scope: { title:'@' },
- *             template: '<div style="border: 1px solid black;">' +

- * @ngdoc directive
- * @name select
- * @restrict E
- *
- * @description
- * HTML `select` element with angular data-binding.
- *
- * The `select` directive is used together with {@link ngModel `ngModel`} to provide data-binding
- * between the scope and the `<select>` control (including setting default values).
- * It also handles dynamic `<option>` elements, which can be added using the {@link ngRepeat `ngRepeat}` or
- * {@link ngOptions `ngOptions`} directives.
- *
- * When an item in the `<select>` menu is selected, the value of the selected option will be bound
- * to the model identified by the `ngModel` directive. With static or repeated options, this is
- * the content of the `value` attribute or the textContent of the `<option>`, if the value attribute is missing.
- * Value and textContent can be interpolated.
- *
- * ## Matching model and option values
- *
- * In general, the match between the model and an option is evaluated by strictly comparing the model
- * value against the value of the available options.
- *
- * If you are setting the option value with the option's `value` attribute, or textContent, the
- * value will always be a `string` which means that the model value must also be a string.
- * Otherwise the `select` directive cannot match them correctly.
- *
- * To bind the model to a non-string value, you can use one of the following strategies:
- * - the {@link ng.ngOptions `ngOptions`} directive
- *   ({@link ng.select#using-select-with-ngoptions-and-setting-a-default-value})
- * - the {@link ng.ngValue `ngValue`} directive, which allows arbitrary expressions to be
- *   option values ({@link ng.select#using-ngvalue-to-bind-the-model-to-an-array-of-objects Example})
- * - model $parsers / $formatters to convert the string value
- *   ({@link ng.select#binding-select-to-a-non-string-value-via-ngmodel-parsing-formatting Example})
- *
- * If the viewValue of `ngModel` does not match any of the options, then the control
- * will automatically add an "unknown" option, which it then removes when the mismatch is resolved.
- *
- * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
- * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
- * option. See example below for demonstration.
- *
- * ## Choosing between `ngRepeat` and `ngOptions`
- *
- * In many cases, `ngRepeat` can be used on `<option>` elements instead of {@link ng.directive:ngOptions
- * ngOptions} to achieve a similar result. However, `ngOptions` provides some benefits:
- * - more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the
- * comprehension expression
- * - reduced memory consumption by not creating a new scope for each repeated instance
- * - increased render speed by creating the options in a documentFragment instead of individually
- *
- * Specifically, select with repeated options slows down significantly starting at 2000 options in
- * Chrome and Internet Explorer / Edge.
- *
- *
- * @param {string} ngModel Assignable angular expression to data-bind to.
- * @param {string=} name Property name of the form under which the control is published.
- * @param {string=} multiple Allows multiple options to be selected. The selected values will be
- *     bound to the model as an array.
- * @param {string=} required Sets `required` validation error key if the value is not entered.
- * @param {string=} ngRequired Adds required attribute and required validation constraint to
- * the element when the ngRequired expression evaluates to true. Use ngRequired instead of required
- * when you want to data-bind to the required attribute.
- * @param {string=} ngChange Angular expression to be executed when selected option(s) changes due to user
- *    interaction with the select element.
- * @param {string=} ngOptions sets the options that the select is populated with and defines what is
- * set on the model on selection. See {@link ngOptions `ngOptions`}.
- *

-/**
- * @ngdoc directive
- * @name ngRequired
- * @restrict A
- *
- * @description
- *
- * ngRequired adds the required {@link ngModel.NgModelController#$validators `validator`} to {@link ngModel `ngModel`}.
- * It is most often used for {@link input `input`} and {@link select `select`} controls, but can also be
- * applied to custom controls.
- *
- * The directive sets the `required` attribute on the element if the Angular expression inside
- * `ngRequired` evaluates to true. A special directive for setting `required` is necessary because we
- * cannot use interpolation inside `required`. See the {@link guide/interpolation interpolation guide}
- * for more info.
- *
- * The validator will set the `required` error key to true if the `required` attribute is set and
- * calling {@link ngModel.NgModelController#$isEmpty `NgModelController.$isEmpty`} with the
- * {@link ngModel.NgModelController#$viewValue `ngModel.$viewValue`} returns `true`. For example, the
- * `$isEmpty()` implementation for `input[text]` checks the length of the `$viewValue`. When developing
- * custom controls, `$isEmpty()` can be overwritten to account for a $viewValue that is not string-based.
- *
- * @example
- * <example name="ngRequiredDirective" module="ngRequiredExample">
- *   <file name="index.html">
- *     <script>

- *
- * <div class="alert alert-info">

-Bindonce
-========
-
-High performance binding for AngularJs
-
-## Usage
-* download, clone or fork it or install it using [bower](http://twitter.github.com/bower/) `bower install angular-bindonce`
-* Include the `bindonce.js` script provided by this component into your app.
-* Add `'pasvaz.bindonce'` as a module dependency to your app: `angular.module('app', ['pasvaz.bindonce'])`
-
-## Demo
-Here is an example of how AngularJs can [freeze your UI](http://plnkr.co/edit/jwrHVb?p=preview), try to press and hold a key inside the input field, when the table is filled with only 1 person everything is ok, you can see how the DOM is updated by the input in real time, however if you try to load 1000 person *(or even 500 if the testing device is not powerfull)* and repeat the experiment you can see how the UI is frozen. In [this other demo](http://plnkr.co/edit/0DGOrk?p=preview) BindOnce will take care of your watchers and the UI will be reactive as it should be. The code is the same for both demos, the only difference is that I replaced any `ng-*` tag inside the table with the equivalent `bo-*` tag.
-* [AngularJs regular Demo](http://plnkr.co/edit/jwrHVb?p=preview)
-* [Demo with Bindonce](http://plnkr.co/edit/0DGOrk?p=preview)
-
-## Overview
-AngularJs provides a great data binding system but if you abuse of it the page can run into some performance issues, it's known that more of 2000 watchers can lag the UI and that amount can be reached easily if you don't pay attention to the data-binding. Sometime you really need to bind your data using watchers, especially for SPA because the data are updated in real time, but often you can avoid it with some efforts, most of the data presented in your page, once rendered, are immutable so you shouldn't keep watching them for changes.
-
-For instance, take a look to this snippet:
-```html
-<ul>
-	<li ng-repeat="person in Persons">
-		<a ng-href="#/people/{{person.id}}"><img ng-src="{{person.imageUrl}}"></a>
-		<a ng-href="#/people/{{person.id}}"><span ng-bind="person.name"></span></a>
-		<p ng-class="{'cycled':person.generated}" ng-bind-html-unsafe="person.description"></p>
-	</li>
-</ul>
-```
-Angular internally creates a `$watch` for each `ng-*` directive in order to keep the data up to date, so in this example just for displaying few info it creates 6 + 1 *(ngRepeatWatch)* watchers per `person`, even if the `person` is supposed to remain the same once shown. Iterate this amount for each person and you can have an idea about how easy is to reach 2000 watchers. Now if you need it because those data could change while you show the page or are bound to some models, it's ok. But most of the time they are static data that don't change once rendered. This is where **bindonce** can really help you.
-
-The above example done with **bindonce**:
-```html
-<ul>
-	<li bindonce ng-repeat="person in Persons">
-		<a bo-href="'#/people/' + person.id"><img bo-src="person.imageUrl"></a>
-		<a bo-href="'#/people/' + person.id" bo-text="person.name"></a>
-		<p bo-class="{'cycled':person.generated}" bo-html="person.description"></p>
-	</li>
-</ul>
-```
-Now this example uses **0 watches** per `person` and renders exactly the same result as the above that uses ng-*. *(Angular still uses 1 watcher for ngRepeatWatch)*
-
-### The smart approach
-OK until here nothing completely new, with a bit of efforts you could create your own directive and render the `person` inside the `link` function, or you could use [watch fighters](https://github.com/abourget/abourget-angular) that has a similar approach, but there is still one problem that you have to face and **bindonce** already handles it: *the existence of the data when the directive renders the content*. Usually the directives, unless you use watchers or bind their attributes to the scope (still a watcher), render the content when they are loaded into the markup, but if at that given time your data is not available, the directive can't render it. Bindonce can wait until the data is ready before to rendering the content.
-Let's take a look at the follow snippet to better understand the concept:
-```html
-<span my-custom-set-text="Person.firstname"></span>
-<span my-custom-set-text="Person.lastname"></span>
-...
-<script>
-angular.module('testApp', [])
-.directive('myCustomSetText', function () {
-	return {
-		link:function (scope, elem, attr, ctrl) {
-			elem.text(scope.$eval(attr.myCustomSetText));
-		}
-	}
-});
-</script>
-```
-This basic directive works as expected, it renders the `Person` data without using any watchers. However, if `Person` is not yet available inside the $scope when the page is loaded (say we get `Person` via $http or via $resource), the directive is useless, `scope.$eval(attr.myCustomSetText)` simply renders nothing and exits.
-
-Here is how we can solve this issue with **bindonce**:
-```html
-<div bindonce="Person" bo-title="Person.title">
-	<span bo-text="Person.firstname"></span>
-	<span bo-text="Person.lastname"></span>
-	<img bo-src="Person.picture" bo-alt="Person.title">
-	<p bo-class="{'fancy':Person.isNice}" bo-html="Person.story"></p>
-</div>
-```
-`bindonce="Person"` does the trick, any `bo-*` attribute belonging to `bindonce` waits until the parent `bindonce="{somedata}"` is validated and then renders its content. Once the scope contains the value `Person` then each bo-* child gets filled with the proper values. In order to accomplish this task, **bindonce** uses just **one** temporary watcher, no matters how many children need to be rendered. As soon as it gets `Person` the watcher is promptly removed. If the $scope already contains the data `bindonce` is looking for, then it doesn't create the temporary watcher and simply starts rendering its children.
-
-You may have noticed that the first example didn't assign any value to the `bindonce` attribute:
-```html
-<ul>
-	<li bindonce ng-repeat="person in Persons">
-	...
-```
-when used with `ng-repeat` `bindonce` doesn't need to check if `person` is defined because `ng-repeat` creates the directives only when `person` exists. You could be more explicit: `<li bindonce="person" ng-repeat="person in Persons">`, however assigning a value to `bindonce` in an `ng-repeat` won't make any difference.
-
-### Interpolation
-Some directives (ng-href, ng-src) use interpolation, ie: `ng-href="/profile/{{User.profileId}}"`.
-Both `ng-href` and `ng-src` have the bo-* equivalent directives: `bo-href-i` and `bo-src-i` (pay attention to the **-i**, it stands for **interpolate**). As expected they don't use watchers however Angular creates one watcher per  interpolation, for instance `bo-href-i="/profile/{{User.profileId}}"` sets the element's href **once**, as expected, but Angular keeps a watcher active on `{{User.profileId}}` even if `bo-href-i` doesn't use it.
-That's why by default the `bo-href` doesn't use interpolation or watchers. The above equivalent with 0 watchers would be `bo-href="'/profile/' + User.profileId"`. Nevertheless, `bo-href-i` and `bo-src-i` are still maintained for compatibility reasons.
-
-### Filters
-Almost every `bo-*` directive replace the equivalent `ng-*` and works in the same ways, except it is evaluated once. 
-Consequentially you can use any valid angular expression, including filters. This is an example how to use a filter:
-```html
-<div bindonce="Person">
-	<span bo-bind="Person.bill | currency:'USD$'"></span>
-</div>
-```
-
-## Attribute Usage
-| Directive  | 	Description | 	Example  |
-|------------|----------------|-----|
-| `bindonce="{somedata}"`| **bindonce** is the main directive. `{somedata}` is optional, and if present, forces bindonce to wait until `somedata` is defined before rendering its children  | `<div bindonce="Person">...<div>` |
-| `bo-if = "condition"`     | equivalent to `ng-if` but doesn't use watchers |`<ANY bo-if="Person.isPublic"></ANY>`|
-| `bo-switch = "expression"`     | equivalent to `ng-switch` but doesn't use watchers |`<div bo-switch="Person.isPublic">` `<span bo-switch-when="'yes">public</span>` `<span bo-switch-default>private</span>` `</div>`|
-| `bo-show = "condition"`     | equivalent to `ng-show` but doesn't use watchers |`<ANY bo-show="Person.isPublic"></ANY>`|
-| `bo-hide = "condition"`     | equivalent to `ng-hide` but doesn't use watchers |`<ANY bo-hide="Person.isPrivate"></ANY>`|
-| `bo-disabled = "condition"`     | equivalent to `ng-disabled` but doesn't use watchers |`<ANY bo-disabled="Person.isUnavailable"></ANY>`|
-| `bo-text = "text"`      | evaluates "text" and print it as text inside the element | `<span bo-text="Person.name"></span>` |
-| `bo-bind = "text"`      | alias for `bo-text`, equivalent to `ng-bind` but doesn't use watchers | `<span bo-bind="Person.name"></span>` |
-| `bo-html = "markup"`      | evaluates "markup" and render it as html inside the element |`bo-html="Person.description"`|
-| `bo-href-i = "url"`<br>*use `bo-href` instead* | **equivalent** to `ng-href`.<br>**Heads up!** Using interpolation `{{}}` it creates one watcher: <br>`bo-href-i="/p/{{Person.id}}"`. <br>Use `bo-href` to avoid the watcher:<br> `bo-href="'/p/' + Person.id"` |`<a bo-href-i="/profile{{Person.id}}"></a>`|
-| `bo-href = "url"`      | **similar** to `ng-href` but doesn't allow interpolation using `{{}}` like `ng-href`. <br>**Heads up!** You can't use interpolation `{{}}` inside the url, use bo-href-i for that purpose |`<a bo-href="'/profile' + Person.id"></a>` <br />or<br /> `<a bo-href="link" bo-text="Link"></a>`|
-| `bo-src-i = "url"`<br>*use `bo-src` instead* | **equivalent** to `ng-src`. <br>**Heads up!** It creates one watcher |`<img bo-src-i="{{picture}}" bo-alt="title">`|
-| `bo-src = "url"`      | **similar** to `ng-src` but doesn't allow interpolation using `{{}}` like `ng-src`. <br>**Heads up!** You can't use interpolation `{{}}`, use bo-src-i for that purpose |`<img bo-src="picture" bo-alt="title">`|
-| `bo-class = "object/string"`      | equivalent to `ng-class` but doesn't use watchers |`<span bo-class="{'fancy':Person.condition}">`|
-| `bo-alt = "text"`      | evaluates "text" and render it as `alt` for the element |`<ANY bo-alt="title">`|
-| `bo-title = "text"`      | evaluates "text" and render it as `title` for the element |`<ANY bo-title="title">`|
-| `bo-id = "#id"`      | evaluates "#id" and render it as `id` for the element |`<ANY bo-id="id">`|
-| `bo-style = "object"`      | equivalent to `ng-style` but doesn't use watchers |`<ANY bo-style="{'color':Person.color}">`|
-| `bo-value = "expression"`      | evaluates "expression" and render it as `value` for the element |`<input type="radio" bo-value="value">`|
-| `bo-attr bo-attr-foo = "text"`      | evaluates "text" and render it as a custom attribute for the element |`<div bo-attr bo-attr-foo="bar"></div>`|

-Angular-DragDrop is a angular HTML5 Drag and Drop directive written in pure with no dependency on JQuery.
-
-This is based on the work done by Jason Turim. While this [blog post](http://jasonturim.wordpress.com/2013/09/01/angularjs-drag-and-drop/) was the inspiration for creating a native Drag and Drop solution, the intention was to create something that was more generic. 
-
-This implementation is mainly different from the one posted in the blog in the following areas : 
-
-1. Angular-DragDrop does not create an isolate scope. This has huge benefits when it comes to working with other directives. **NOTE :** It also does not pollute the scope with any variables or functions.
-
-2. It does not depend on any kind of an ID attribute ( being either present or generated on the fly ). 
-
-3. It allows one to create channels on which different drag and drop directive combinations can work on in the same page ( more on this later ) . 
-
-Pull requests are welcome.

-# Angular Drag and Drop
-**A Native ( without jquery ) Drag and Drop directive for AngularJS using HTML5 Drag and Drop**
-
----
-
-##ui-draggable(expression)
-
-Directive in module ang-drag-drop (since 1.0.5 - old module name ngDragDrop)
-
-The ui-draggable attribute tells Angular that the element is draggable. ui-draggable takes an expression as the attribute value. The expression should evaluate to either true or false. You can toggle the draggability of an element using this expression.
-
-###Additional Attributes
-
-####_**drag**_(variable)
-
-The class used to mark child elements of draggable object to be used as drag handle. Default class name is `drag-handle`
-
-**NOTE**: If attribute is not present drag handle feature is not active.
-
-
-
-####_**drag-handle-class**_(string)
-
-The `drag` property is used to assign the data that needs to be passed along with the dragging element.
-
-
-
-
-####_**on-drop-success**_(function)
-
-The `on-drop-success` attribute takes a function. We can consider this to be an on-drop-success handler function. This can be useful if you need to do some post processing after the dragged element is dropped successfully on the drop site.
-
-**NOTE**: This callback function is only called when the drop succeeds.
-You can request the `drag-end` event ( very similiar to requesting the click event in `ng-click` ) by passing `$event` in the event handler.
-
-
-
-####_**on-drop-failure**_(function)
-
-The `on-drop-failure` attribute takes a function. We can consider this to be an on-drop-failure handler function. This can be useful if you need to do some post processing after the dragged element is dropped unsuccessfully on any drop site.
-
-**NOTE**: This callback function is only called when the drop fails.
-You can request the `drag-end` event ( very similiar to requesting the click event in `ng-click` ) by passing `$event` in the event handler.
-
-
-
-####_**drag-channel**_(string)
-
-The `on-drop-failure` attribute takes a function. We can consider this to be an on-drop-failure handler function. This can be useful if you need to do some post processing after the dragged element is dropped unsuccessfully on any drop site.
-
-**NOTE**: This callback function is only called when the drop fails.
-You can request the `drag-end` event ( very similiar to requesting the click event in `ng-click` ) by passing `$event` in the event handler.
-
-
-
-###Usage
-
-
-
-###Events
-
-On start of dragging an Angular Event `ANGULAR_DRAG_START` is dispatched from the `$rootScope`. The event also carries carries the information about the channel in which the dragging has started.
-
-On end of dragging an Angular Event `ANGULAR_DRAG_END` is dispatched from the `$rootScope`. The event also carries carries the information about the channel in which the dragging has started.
-
-When hovering a draggable element on top of a drop area an Angular Event `ANGULAR_HOVER` is dispatched from the `$rootScope`. The event also carries the information about the channel in which the dragging has started.
-
----
-
-##ui-on-drop(expression)
-
-Directive in module ang-drag-drop (since 1.0.5 - old module name ngDragDrop)
-
-The `ui-on-drop` attribute tells Angular that the element is a drop site. `ui-on-drop` takes a function as the attribute value. The function will be called when a valid dragged element is dropped in that location. A valid dragged element is one which has the same channel as the drop location.
-
-**NOTE** : This callback function is only called when the drop succeeds.
-The `ui-on-drop` callback can request additional parameters. The data that is dragged is available to the callback as $data and its channel as `$channel`. Apart from this the drop event is exposed as `$event`.
-
-###Additional Attributes
-
-####_**drop-channel**_(variable)
-
-The channel that the drop site accepts. The dragged element should have the same channel as this drop site for it to be droppable at this location. It is possible to provide comma separated list of channels.
-
-**NOTE**: Also special value of `drag-channel` attribute is available to accept dragged element with any channel value — *
-
-
-
-####_**drop-validate**_(function)
-
-Extra validation that makes sure that the drop site accepts the dragged element beyond having the same channel. If not defined, no extra validation is made.
-
-**NOTE**: This callback function is called only if the channel condition is met, when the element starts being dragged
-
-
-
-
-####_**drag-enter-class**_(string)
-
-The class that will be added to the the droppable element when a dragged element ( which is droppable ) enters the drop location. The default value for this is `on-drag-enter`
-
-
-
-####_**drag-hover-class**_(string)
-
-The class that will be added to the drop area element when hovering with an element. The default value for this is `on-drag-hover`
-
-
-
-###Usage
-
-
-
-###Events
-
-On start of dragging an Angular Event `ANGULAR_DRAG_START` is dispatched from the `$rootScope`. The event also carries carries the information about the channel in which the dragging has started.
-
-On end of dragging an Angular Event `ANGULAR_DRAG_END` is dispatched from the `$rootScope`. The event also carries carries the information about the channel in which the dragging has started.
-
-When hovering a draggable element on top of a drop area an Angular Event `ANGULAR_HOVER` is dispatched from the `$rootScope`. The event also carries the information about the channel in which the dragging has started.

-# Contributing guide
-
-Want to contribute to Clipboard.js? Awesome!
-There are many ways you can contribute, see below.
-
-## Opening issues
-
-Open an issue to report bugs or to propose new features.
-
-- Reporting bugs: describe the bug as clearly as you can, including steps to reproduce, what happened and what you were expecting to happen. Also include browser version, OS and other related software's (npm, Node.js, etc) versions when applicable.
-
-- Proposing features: explain the proposed feature, what it should do, why it is useful, how users should use it. Give us as much info as possible so it will be easier to discuss, access and implement the proposed feature. When you're unsure about a certain aspect of the feature, feel free to leave it open for others to discuss and find an appropriate solution.
-
-## Proposing pull requests
-
-Pull requests are very welcome. Note that if you are going to propose drastic changes, be sure to open an issue for discussion first, to make sure that your PR will be accepted before you spend effort coding it.
-
-Fork the Clipboard.js repository, clone it locally and create a branch for your proposed bug fix or new feature. Avoid working directly on the master branch.
-
-Implement your bug fix or feature, write tests to cover it and make sure all tests are passing (run a final `npm test` to make sure everything is correct). Then commit your changes, push your bug fix/feature branch to the origin (your forked repo) and open a pull request to the upstream (the repository you originally forked)'s master branch.
-
-## Documentation
-
-Documentation is extremely important and takes a fair deal of time and effort to write and keep updated. Please submit any and all improvements you can make to the repository's docs.
-
-## Known issues
-If you're using npm@3 you'll probably face some issues related to peerDependencies.

-![Killing Flash](https://img.shields.io/badge/killing-flash-brightgreen.svg?style=flat)
-
-> Modern copy to clipboard. No Flash. Just 3kb gzipped.
-
-<a href="https://clipboardjs.com/"><img width="728" src="https://cloud.githubusercontent.com/assets/398893/16165747/a0f6fc46-349a-11e6-8c9b-c5fd58d9099c.png" alt="Demo"></a>
-
-## Why
-
-Copying text to the clipboard shouldn't be hard. It shouldn't require dozens of steps to configure or hundreds of KBs to load. But most of all, it shouldn't depend on Flash or any bloated framework.
-
-That's why clipboard.js exists.
-
-## Install
-
-You can get it on npm.
-
-```
-npm install clipboard --save
-```
-
-Or bower, too.
-
-```
-bower install clipboard --save
-```
-
-If you're not into package management, just [download a ZIP](https://github.com/zenorocha/clipboard.js/archive/master.zip) file.
-
-## Setup
-
-First, include the script located on the `dist` folder or load it from [a third-party CDN provider](https://github.com/zenorocha/clipboard.js/wiki/CDN-Providers).
-
-```html
-<script src="dist/clipboard.min.js"></script>
-```
-
-Now, you need to instantiate it by [passing a DOM selector](https://github.com/zenorocha/clipboard.js/blob/master/demo/constructor-selector.html#L18), [HTML element](https://github.com/zenorocha/clipboard.js/blob/master/demo/constructor-node.html#L16-L17), or [list of HTML elements](https://github.com/zenorocha/clipboard.js/blob/master/demo/constructor-nodelist.html#L18-L19).
-
-```js
-new Clipboard('.btn');
-```
-
-Internally, we need to fetch all elements that matches with your selector and attach event listeners for each one. But guess what? If you have hundreds of matches, this operation can consume a lot of memory.
-
-For this reason we use [event delegation](http://stackoverflow.com/questions/1687296/what-is-dom-event-delegation) which replaces multiple event listeners with just a single listener. After all, [#perfmatters](https://twitter.com/hashtag/perfmatters).
-
-# Usage
-
-We're living a _declarative renaissance_, that's why we decided to take advantage of [HTML5 data attributes](https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Using_data_attributes) for better usability.
-
-### Copy text from another element
-
-A pretty common use case is to copy content from another element. You can do that by adding a `data-clipboard-target` attribute in your trigger element.
-
-The value you include on this attribute needs to match another's element selector.
-
-<a href="https://clipboardjs.com/#example-target"><img width="473" alt="example-2" src="https://cloud.githubusercontent.com/assets/398893/9983467/a4946aaa-5fb1-11e5-9780-f09fcd7ca6c8.png"></a>
-
-```html
-<!-- Target -->
-<input id="foo" value="https://github.com/zenorocha/clipboard.js.git">
-
-<!-- Trigger -->
-<button class="btn" data-clipboard-target="#foo">
-    <img src="assets/clippy.svg" alt="Copy to clipboard">
-</button>
-```
-
-### Cut text from another element
-
-Additionally, you can define a `data-clipboard-action` attribute to specify if you want to either `copy` or `cut` content.
-
-If you omit this attribute, `copy` will be used by default.
-
-<a href="https://clipboardjs.com/#example-action"><img width="473" alt="example-3" src="https://cloud.githubusercontent.com/assets/398893/10000358/7df57b9c-6050-11e5-9cd1-fbc51d2fd0a7.png"></a>
-
-```html
-<!-- Target -->
-<textarea id="bar">Mussum ipsum cacilds...</textarea>
-
-<!-- Trigger -->
-<button class="btn" data-clipboard-action="cut" data-clipboard-target="#bar">
-    Cut to clipboard
-</button>
-```
-
-As you may expect, the `cut` action only works on `<input>` or `<textarea>` elements.
-
-### Copy text from attribute
-
-Truth is, you don't even need another element to copy its content from. You can just include a `data-clipboard-text` attribute in your trigger element.
-
-<a href="https://clipboardjs.com/#example-text"><img width="147" alt="example-1" src="https://cloud.githubusercontent.com/assets/398893/10000347/6e16cf8c-6050-11e5-9883-1c5681f9ec45.png"></a>
-
-```html
-<!-- Trigger -->
-<button class="btn" data-clipboard-text="Just because you can doesn't mean you should — clipboard.js">
-    Copy to clipboard
-</button>
-```
-
-## Events
-
-There are cases where you'd like to show some user feedback or capture what has been selected after a copy/cut operation.
-
-That's why we fire custom events such as `success` and `error` for you to listen and implement your custom logic.
-
-```js
-var clipboard = new Clipboard('.btn');
-
-clipboard.on('success', function(e) {
-    console.info('Action:', e.action);
-    console.info('Text:', e.text);
-    console.info('Trigger:', e.trigger);
-
-    e.clearSelection();
-});
-
-clipboard.on('error', function(e) {
-    console.error('Action:', e.action);
-    console.error('Trigger:', e.trigger);
-});
-```
-
-For a live demonstration, open this [site](https://clipboardjs.com/) and just your console :)
-
-## Advanced Options
-
-If you don't want to modify your HTML, there's a pretty handy imperative API for you to use. All you need to do is declare a function, do your thing, and return a value.
-
-For instance, if you want to dynamically set a `target`, you'll need to return a Node.
-
-```js
-new Clipboard('.btn', {
-    target: function(trigger) {
-        return trigger.nextElementSibling;
-    }
-});
-```
-
-If you want to dynamically set a `text`, you'll return a String.
-
-```js
-new Clipboard('.btn', {
-    text: function(trigger) {
-        return trigger.getAttribute('aria-label');
-    }
-});
-```
-
-Also, if you are working with single page apps, you may want to manage the lifecycle of the DOM more precisely. Here's how you clean up the events and objects that we create.
-
-```js
-var clipboard = new Clipboard('.btn');
-clipboard.destroy();
-```
-
-## Browser Support
-
-This library relies on both [Selection](https://developer.mozilla.org/en-US/docs/Web/API/Selection) and [execCommand](https://developer.mozilla.org/en-US/docs/Web/API/Document/execCommand) APIs. The first one is [supported by all browsers](http://caniuse.com/#search=selection) while the second one is supported in the following browsers.
-
-| <img src="https://clipboardjs.com/assets/images/chrome.png" width="48px" height="48px" alt="Chrome logo"> | <img src="https://clipboardjs.com/assets/images/edge.png" width="48px" height="48px" alt="Edge logo"> | <img src="https://clipboardjs.com/assets/images/firefox.png" width="48px" height="48px" alt="Firefox logo"> | <img src="https://clipboardjs.com/assets/images/ie.png" width="48px" height="48px" alt="Internet Explorer logo"> | <img src="https://clipboardjs.com/assets/images/opera.png" width="48px" height="48px" alt="Opera logo"> | <img src="https://clipboardjs.com/assets/images/safari.png" width="48px" height="48px" alt="Safari logo"> |
-|:---:|:---:|:---:|:---:|:---:|:---:|
-| 42+ ✔ | 12+ ✔ | 41+ ✔ | 9+ ✔ | 29+ ✔ | 10+ ✔ |
-
-The good news is that clipboard.js gracefully degrades if you need to support older browsers. All you have to do is show a tooltip saying `Copied!` when `success` event is called and `Press Ctrl+C to copy` when `error` event is called because the text is already selected.

 The Singlestat Panel allows you to show the one main summary stat of a SINGLE series.

 ### Coloring
 
 The coloring options of the Singlestat Panel config allow you to dynamically change the colors based on the Singlestat value.
 
-<img class="no-shadow" src="/img/docs/v1/Singlestat-Coloring.png">

-2. `Value`: This checkbox applies the configured thresholds and colors to the summary stat.
-3. `Thresholds`: Change the background and value colors dynamically within the panel, depending on the Singlestat value. The threshold field accepts **2 comma-separated** values which represent 3 ranges that correspond to the three colors directly to the right.

 ### Spark Lines
 
 Sparklines are a great way of seeing the historical data related to the summary stat, providing valuable context at a glance. Sparklines act differently than traditional Graph Panels and do not include x or y axis, coordinates, a legend, or ability to interact with the graph.
 
-<img class="no-shadow" src="/img/docs/v1/Singlestat-Sparklines.png">

 1. `Show`: The show checkbox will toggle whether the spark line is shown in the Panel. When unselected, only the Singlestat value will appear.
-2. `Background`: Check if you want the sparklines to take up the full panel width, or uncheck if they should be below the main Singlestat value.
+2. `Full Height`: Check if you want the sparklines to take up the full panel height, or uncheck if they should be below the main Singlestat value.
 3. `Line Color`: This color selection applies to the color of the sparkline itself.
 4. `Fill Color`: This color selection applies to the area below the sparkline.
 
 > ***Pro-tip:*** Reduce the opacity on  fill colors for nice looking panels.
 
+### Gauge
+
+Gauges gives a clear picture of how high a value is in it's context. It's a great way to see if a value is close to the thresholds. The gauge uses the colors set in the color options.
+

+
+1. `Show`: The show checkbox will toggle wether the gauge is shown in the panel. When unselected, only the Singlestat value will appear.

+3. `Threshold Labels`: Check if you want to show the threshold labels. Thresholds are set in the color options.
+4. `Threshold Markers`: Check if you want to have a second meter showing the thresholds.

 ### Value to text mapping
 
-Value to text mapping allows you to translate the value of the summary stat into explicit text. The text will respect all styling, thresholds and customization defined for the value. This can be useful to translate the number of the main Singlestat value into a context-specific human-readable word or message.

 Grafana 2.5 introduced stricter checking for multiple-series on singlestat panels. In previous versions, the panel logic did not verify that only a single series was used, and instead, displayed the first series encountered. Depending on your data source, this could have lead to inconsistent data being shown and/or a general confusion about which metric was being displayed.

 The Singlestat Panel allows you to show the one main summary stat of a SINGLE series. It reduces the series into a single number (by looking at the max, min, average, or sum of values in the series). Singlestat also provides thresholds to color the stat or the Panel background. It can also translate the single number into a text value, and show a sparkline summary of the series.

 Value to text mapping allows you to translate the value of the summary stat into explicit text. The text will respect all styling, thresholds and customization defined for the value. This can be useful to translate the number of the main Singlestat value into a context-specific human-readable word or message.
