* Add statistics enum
* Support ensemble statistics curve as data source for regression curves
* Allow creation of regression curves from statistics curves
* Make sure regression curves are updated after source curves
* Add state to use full or user defined range for regression source data
* Add isRegressionCurve
* Make sure source stepping works when regression curves are present
* Verify vector size only for cross plot regression curves
* Add filtering on axis orientation
Makes it possible to show only horizontal or vertical axes when selecting an axis to attach a curve to.
* Send curvesChanged signal to trigger multi plot updates
This signal will trigger update of axes and set correct scaling factor
* Use object name for axis object
* Use address for both x and y axis to create ensemble curve name
* Fix bug for drag/drop of ensemble object into plot
* Add RiaSummaryCurveAddress to RiaSummaryCurveDefinition
* Remove SummaryDataSource
* Use childFieldChangedByUi to trigger update of curves and titles
* Use one common variable for object name, use three ints
* Move enums to separate file
* Refactor use of enums
* Move implementation to cpp
* Refactor includes
* Update icons for summary and ensemble templates
* Icons for regression and decline
* #10374 LineEditor: Hide the placeholder widget when not used
* #10376 Assign a case ID to delta summary case
* Do not show decline range text in plot
* Regression Analysis: Use only positive values for Power Fit regression.
* Add visible tag short cut for changning curve color.
* #10214 Ensemble Curve Set: Fix color mode text.
* #10214 Ensemble: Switch P10 and P90 symbols to point towards mean.
* Cache hit rects for tree item tags.
* #10214 Ensemble curve set: allow reordering with tree view tag
* #10214 Keep curve legend text when ensemble curves are hidden
