#2276:

  • Implemented a ModifiableDatasetView which allows values in the modifiable dataset to be visually edited.
  • Made SetValue and Validate implementations explicit in the Dataset class
  • Added explicit implementations of SetValue and Validate in the ModifiableDataset
  • Renamed ChangeVariableValue method to SetVariableValue for consistency
