Tests if this user can change the hierarchy.

        A return of true does not guarantee successful authorization. A
        return of false indicates that it is known performing any update
        will result in a ``PermissionDenied``. This is intended as a
        hint to an application that may opt not to offer these
        operations to an unauthorized user.

        return: (boolean) - ``false`` if changing this hierarchy is not
                authorized, ``true`` otherwise
        *compliance: mandatory -- This method must be implemented.*
