| This class acts as a front end to a FormUndoableEdit. It behaves in exactly
the same way as the delegate however, we add the concept of a locked state.
Since we share edit objects between opened editors, we can put the locked
flag in the delegate.
We need to lock an edit when we are editing a form in two different editors.
This can happen if the form is nested. If the undo managers for the editors
get out of sync (which can easily happen) then we need to lock the edits that
are out of sync.
