Look 'n' Feel and implementation logic are inspired from
'http://explain.depsez.com'.
It now creates three tabs under the 'Explain' panel when executing a
query using the Explain Analyze/Explain button from the toolbar of the
Query tool.
Graphical
---------
-> Graphical Explain Plan
Analysis
--------
-> Table to show details of the explain plan analyse.
-> Each row represents the statistics per Explain Plan Node
-> It may contains columns like node information, exclusive timing
(time spent for this explain node excluding the child nodes),
inclusive timing, actual rows, plan rows,
rowsx (misestimation between planned vs actual rows), loop.
-> Background color of exclusive, inclusive, rows changes based on
their values.
i.e.
If Percentage of exclusive, and inclusive timings of total query time
is:
> 90 - Red Color
> 50 - Orange (Between Red & Yellow Color)
> 10 - Yellow color
If planner misestimation for the rows is
> 1000 times - Red Color
> 100 times - Orange (Between Red & Yellow Color)
> 10 times - Yellow Color
Also - if actual rows <= planned rows then it shows up arrow, else it
shows down arrow.
Statistics
----------
-> It contains a HTML table for the statistics per Node Type, and
a HTML table for the statistics per table.

This patch takes care of:
* Consistent behaviour during create, update operation on any node.
- It should return the node data during creating a new object, or
updating the existing one.
* Now that - we have consistent behaviour during these operations, we
can consistently move, update the tree item based the node data from
the server.
* Implemented the methods for each node to get the information about
that particular node only.
* Using the above changes to implement the 'refresh' operation on tree
node properly.
I must thank Surinder, and Harshal for helping me implement the 'node'
method, and also changed the behaviour of create & update methods to
return the node data for most of the nodes.
Fixes#1244
(lazy loading) using the require.js. This allows us to load the
javascript required for any node, only when it was loaded in the browser
tree. Also, introduced the mechanism to show/edit/create of any node in
a tab panel (wcDocker.Panel).
