    GUI-Builder:

    this class allows the user to build its own applications providing a graphical

    user interface to buildin components and to define the behavior of the components

    during runtime. The resulting specifications can be installed as methods on 

    classes, typically subclasses of an ApplicationModel. These specifications

    are used by the UIBuilder to generate the application window and its component

    structues when open the application.
