       Broadcasting facilities between clients and server

       type 'a t

       The  type of bus's carrying values of type 'a . Bus's are values that can be easily shared
       among clients. Each of these clients along with the server can send a value  on  the  bus.
       Values can be received by each of the participants as a stream. Note that no effort is put
       to order message receptions on the different participants.

       val create : ?scope:[< Eliom_comet.Channel.comet_scope ] -> ?name:string ->  ?size:int  ->
       'a Deriving_Json.t -> 'a t

       create  ?scope  ?name  ?size makes a fresh bus. The name optional parameter can be used to
       make persistent (as in server restart persistent) bus's. The scope parameter  is  used  to
       chose  the  kind  of  channel  on  which  the  bus  rely  (See Eliom_comet.create for more
       information). The ?name argument allow one to make bus's persistent over  server  restart.
       The size argument behaves like the one on Eliom_comet.Channel.create

       val stream : 'a t -> 'a Lwt_stream.t

       stream  b  returns  the  stream  of  datas  sent  to bus b . Notice you sould not use that
       function multiple times on the same bus, it will return the same stream. If  you  want  to
       receive multiple times the same datas, you sould copy the stream with Lwt_stream.clone

       val write : 'a t -> 'a -> unit

       write  b  x sends the value x on the bus b . Every participant, including the server, will
       receive x .
