    DESCRIPTION:
        The CBandProxy class will allow bands to navigate a
    generic browser window.  This will work correctly if the
    band is tied to the Browser Window because it's a ToolBar.
    Or if it's a toolband, each time a navigation happens,
    the top most browser window needs to be found or a new window 
    created.
