 * 
 * A #DbusmenuMenuitem is the lowest level of represenation of a
 * single item in a menu.  It gets created on the server side
 * and copied over to the client side where it gets rendered.  As
 * the server starts to change it, and grow it, and do all kinds
 * of fun stuff that information is transfered over DBus and the
 * client updates it's understanding of the object model.
 * 
 * Most people using either the client or the server should be
 * able to deal mostly with #DbusmenuMenuitem objects.  These
 * are simple, but then they can be attached to more complex
 * objects and handled appropriately.
