Description Nam Nguyen 2007-05-16 23:15:27 UTC 
The use cases are:
- During multiple mutations transaction client code might need control to
rollback the model to the state before beginTransaction is called.
- Refactoring UI need to start mutations just to get the source of the model as
if refactored, then rollback to original state.

The rollback should also preserve the undo queue.
