Predicate hub_broadcast/2

hub_broadcast(+Hub, +Message) is det
hub_broadcast(+Hub, +Message, :Condition) is det: Send Message to all websockets associated with Hub for which call(Condition, Id) succeeds. Note that this process is asynchronous: this predicate returns immediately after putting all requests in a broadcast queue. If a message cannot be delivered due to a network error, the hub is informed through io_error/3.
