Simple server/client implementation

So, I modified some bits of code I found.

So what is this?

Basically there is a server and a client.
To test, you must run the server first. After that, you run the client. The client sends a message to the server, the server outputs that message to the console, and sends a message back to the client. After the client gets the server message, it outputs that same message to the console and exits.

I think its a good start.
