    """The TraitsUI project contains a toolkit-independent GUI abstraction
    layer, which is used to support the "visualization" features of the Traits
    package. Thus, you can write model in terms of the Traits API and specify a
    GUI in terms of the primitives supplied by TraitsUI (views, items, editors,
    etc.), and let TraitsUI and your selected toolkit and back-end take care of
    the details of displaying them."""
