Tests if this user can perform ``Gradebook`` lookups.

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

        return: (boolean) - ``false`` if lookup methods are not
                authorized, ``true`` otherwise
        *compliance: mandatory -- This method must be implemented.*
