Introduce RimReservoirGridEnsemble and RimReservoirGridEnsembleBase to manage ensembles of grid-only Eclipse cases. Enable detection of identical grids for shared operations and statistics. Integrate grid ensembles into project structure, UI, and menu system. Refactor statistics and view handling to support both case groups and grid ensembles via a common interface. Add deferred grid loading, robust case referencing, and migration for well data source fields. New features and menu items allow creation and management of grid ensembles from file sets, enabling new workflows for grid-only ensemble analysis.
- 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
