GroupChat-using-ZeroMQ

This is a group chat client/server implementation to explore the base ZeroMQ API and some of the higher level patterns.

The client uses multithreading and ZeroMQ's asynchronous I/O model to separately update the message text input interfaces, communicate between components, and send messages and receive replies from the server.

The server simply exposes a port for incoming messages and broadcasts them to all currently connected clients.

ZeroMQ is a high-performance asynchronous messaging library, aimed at use in distributed or concurrent applications.
It provides a message queue, but unlike message-oriented middleware, a ZeroMQ system can run without a dedicated message broker.
