@abc.abstractmethod<EOL><INDENT>def can_create_gradebooks(self):<DEDENT>
return<EOL>
Tests if this user can create ``Gradebooks``.

        A return of true does not guarantee successful authorization. A
        return of false indicates that it is known creating a
        ``Gradebook`` will result in a ``PermissionDenied``. This is
        intended as a hint to an application that may not wish to offer
        create operations to unauthorized users.

        :return: ``false`` if ``Gradebook`` creation is not authorized, ``true`` otherwise
        :rtype: ``boolean``
