public interface UndoEventReceiver
This is a marker interface for hooks. If a PermanentNodeHook implements
this interface (which is easy), it receives onUpdateNodeHook, onUpdateChildrenHook,
even when the action issuing this update is caused by an undo action.
Normally, on undo, no event are generated.
The onAddChild, onAddChildren events are not implemented yet. They are generated in any case.
