    An Autobus bus. Busses manage a set of published services, and allow

    port and multiplexes all published services over it.
    
    Bus is a subclass of ServiceProvider; the service it provides is a service
    exposing information about what other services, events, functions, and
    objects are present. (This service is more commonly known as the
    introspection service.) You normally won't have to know this; instances of
    Bus register themselves as services with themselves, so you don't need to
    do anything to make the introspection service work.
