Tests if this user can update gradebook columns.

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

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