def can_create_relationships(self):
return True<EOL>
Tests if this user can create ``Relationships`` A return of true does not
            guarantee successful authorization.

        A return of false indicates that it is known creating a
        ``Relationship`` will result in a ``PermissionDenied``. This is
        intended as a hint to an application that may opt not to offer
        create operations to an unauthorized user.

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