I think even Grant would agree that when you call "help(make_widget)", 
you should see something like:

    make_widget(styleID, material) -> widget or 
        raise ValueError on failure

        styleID: numeric ID or string name of the widget style
        material: WidgetMaterial instance or None to use default

rather than:

    See source code for details.
