Eclipse grid views and contour maps are not longer a child of the case.
The views are not separate collections (one for grid and one for contour maps)
on root level.
- add data source selection, either Case Property or Grid Calculation
- add Time Step Selection, can be used for both dynamic case properties and Grid Calculations
- optionally release grid calculation data when statistics is computed
- recursive grid calculations is supported
ResInsight assumes that loading of data is done for all time steps at a time. Special handling of data loading is required for statistics calculations. Make statistical class a friend to be able to do this operation.
