RE: [gtkmm] Gtk::TreeModel derivation

The get_value_vfunc() is called the GTK+, to get the data out of the model.
You might override it if you derive a TreeModel.

The get_value_impl() is called by gtkmm's get_value(), or operator[]
methods. They don't do the same thing - they just have similar names.
