Use the first available highlighted curve as basis for display of horizontal readout value. Fallback to single realization curves.
When selecting a realization in project tree, highlight all related curves
Make sure zoom rect works when readout annotations are active
* 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
* Ensemble Curves : Improve visual appearance
Set line thickness to 1
If ensemble curves are bright, use a high saturation color for the highlight curve
Increase line thickness for highlighted curve
* Use color by summary vector phase for ensemble curves
* Do not create curves for non-existing history vectors
