C++ socket example

Example on how to use sockets in C++

• use make client and make server to build
• ./server_test to run the server
• ./client_test to run the client

One could connect to the server also using netcatnc 127.0.0.1 8080 altought not recommended. The purpose it is to connect from multiple clients and replicate a chat server.

A client can close the connection by sending !q as a message. This way server will handle the closing connection properly. The code might be improved by introducing a 'TIME_OUT' for clients which are not active for a while.
