    returning "default_return" upon an exception being thrown.

    This is used to wrap Gtk.TreeModel "do_" method implementations so we can return
    a proper value from the override upon an exception occurring with client code
    implemented by the "on_" methods.

    The GenericTreeModel eases implementing the Gtk.TreeModel interface in Python.
    The class can be subclassed to provide a TreeModel implementation which works
    directly with Python objects instead of iterators.

    All of the on_* methods should be overridden by subclasses to provide the
    underlying implementation a way to access custom model data. For the purposes of
    this API, all custom model data supplied or handed back through the overridable
    API will use the argument names: node, parent, and child in regards to user data
    python objects.

    The create_tree_iter, set_user_data, invalidate_iters, iter_is_valid methods are
    available to help manage Gtk.TreeIter objects and their Python object references.

    GenericTreeModel manages a pool of user data nodes that have been used with iters.
    This pool stores a references to user data nodes as a dictionary value with the
    key being the integer id of the data. This id is what the Gtk.TreeIter objects
    use to reference data in the pool.
    References will be removed from the pool when the model is deleted or explicitly
    by using the optional "node" argument to the "row_deleted" method when notifying
    the model of row deletion.
    Tz�If True, strong references to user data attached to iters are stored in a dictionary pool (default). Otherwise the user data is stored as a raw pointer to a python object without a reference.)�default�typeZblurbcs(tt|�j�d|_t�|_|j�dS)zFInitialize.
