Remarks

When an editing scope is committed, the editing store takes all changes that occurred within it and applies them to the model. If the editing scope's Revert method is called, or the editing scope is disposed of before Complete is called, the editing scope will instead reverse the changes made to the underlying objects, reapplying state from the editing store. This provides a solid basis for an undo mechanism.

Constructors
