@classmethod<EOL><INDENT>def _class_name(cls):<DEDENT>
return cls.__name__<EOL>
Return the class name.

        This overrides Model._class_name() which is an alias for _get_kind().

        This is overridable in case you want to use a different class
        name.  The main use case is probably to maintain backwards
        compatibility with datastore contents after renaming a class.

        NOTE: When overriding this for an intermediate class in your
        hierarchy (as opposed to a leaf class), make sure to test
        cls.__name__, or else all subclasses will appear to have the
        same class name.
