This class guards, within a given scope, the Undo Manager of a document (or another component supporting
the XUndoManagerSupplier interface). When entering the scope (i.e. when the <code>DocumentUndoGuard</code>
instances is constructed), the current state of the undo contexts of the undo manager is examined.
Upon leaving the scope (i.e. when the <code>DocumentUndoGuard</code> is destructed), the guard will execute
as many calls to <member scope="com::sun::star::document">XUndoManager::leaveUndoContext</member> as are
necessary to restore the manager's initial state.
