        Abstract class that defines the required interface for all WindowFactory objects

        A WindowFactory is used to create and destroy windows of a specific type.  For every
        type of Window object wihin the system (widgets, dialogs, movable windows etc) there
        must be an associated WindowFactory registered with the WindowManager so that the system
        knows how to create and destroy those types of Window base object.
