Added example code from README as a test script

test/echoconn.py

+#!/usr/bin/env python

+    def onmessage(self, message):
+        print 'Received message "%s"' % message.payload
+        self.send(wspy.TextMessage(message.payload))
+
+    def onclose(self, code, reason):
+        print 'Connection closed'
+
+server = wspy.websocket()
+server.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
+server.bind(('', 8000))
+server.listen(5)

+try:

+        client, addr = server.accept()
+        EchoConnection(client).receive_forever()
