def is_enabled(self):
pass<EOL>
Tests if this operable is administravely enabled.

        Administratively enabling overrides any applied ``OsidEnabler``.
        If this method returns ``true`` then ``is_disabled()`` must
        return ``false``.

        return: (boolean) - ``true`` if this operable is enabled,
                ``false`` if the active status is determined by other
                rules
        *compliance: mandatory -- This method must be implemented.*
