Tests if this user can alter grade system/gradebook mappings.

        A return of true does not guarantee successful authorization. A
        return of false indicates that it is known mapping methods in
        this session will result in a ``PermissionDenied``. This is
        intended as a hint to an application that may opt not to offer
        assignment operations to unauthorized users.

        arg:    gradebook_id (osid.id.Id): the ``Id`` of the
                ``Gradebook``
        return: (boolean) - ``false`` if mapping is not authorized,
                ``true`` otherwise
        raise:  NullArgument - ``gradebook_id`` is ``null``
