Implements: menu-item-container<%>

     frame : frame% object
     demand-callback = void : procedure of one argument: a menu-bar% object

  Creates a menu bar in the specified frame. The menu bar is initially empty.

  The demand-callback procedure is called by the default on-demand method with the object itself.
