public interface UndoEvent
An UndoEvent is an object that contains everything needed to reset its source
back to a specific state. Used by the UndoStack. This event is used by the
UndoStack to tell other objects to undo/redo - go to a certain state. The
events that tell the UndoStack to make these notifications are regular
ActionEvents, not these.
