In this change router was redesigned in a way most appropriate for routing concept of zmq.ROUTER socket. DEALER(cli)-ROUTER(proxy)-DEALER(srv) instead of DEALER-ROUTER-DEALER-ROUTER (3 layers instead of 4) The main reason is to use zmq.DEALER identity in message routing. For this reason DealerConsumer was introduced server-side. RouterConsumer is left for peer-to-peer DEALER-ROUTER deployment option. Also handled assertions in receive-methods in order to not stop server when received message with wrong format.
