A Simple Request-Reply pattern using ZeroMQ in NodeJS

This is a typical example of simple request-reply socket pattern. A request is made and a reply is given.

Of course, in real world socket messaging it won't be exactly like this. In order to protect the data transmitted over the network,message headers or message envelope may be used to identify the incoming request. The messages transmitted over the network would be encrypted using ZMQ's reliable and handy encryption methods such as **CurveServer**.
