Detailed Description

Creates an event handler into the undo manager to minimize sent events. To use this, create a CH_UndoEventHandler::Scope object on the stack to encapsulate the undo actions that we want to batch events for. If the actions span multiple function calls, use matching undoBegin()/undoEnd() invocations.
