def __init__(self, name=_CLASS_KEY_PROPERTY, indexed=True):
super(_ClassKeyProperty, self).__init__(name=name, indexed=indexed,<EOL>repeated=True)<EOL>
Constructor.

        If you really want to you can give this a different datastore name
        or make it unindexed.  For example::

          class Foo(PolyModel):
            class_ = _ClassKeyProperty(indexed=False)
