- each CNPeer is given a unique chan *protocol.Event to pass events to the service.handleEvents() loop. this is now passed to CNPeer.Handler() as opposed to NewCNPeer(). - service has basically been rewritten. handleEvents() main loop uses reflect.SelectCase() now to handle all of the eRecv channels for each peer - new protocol Event type: EVENT_CLIENT_CONNECT - Added service_test.go; blackbox-styled testing like the others. TestService() starts a service and spins up a bunch of dummy peers and verifies that each packet sent causes the corresponding packet handler to be called.
