NetworkEgress

A boundary port through which QObject instances leave a StationNetwork. An egress performs the network's exit bookkeeping (decrement the number in system, record the system time, count the completion, publish the exited-network event) and then either disposes of the instance or hands it off to an external receiver.

A SinkStation is the self-contained special case of an egress that disposes of the instances it receives.
