Added Server and RequestHandler file

Planned the implementation in basically following two parts :

1. Server - Handles th connection with the client and passes the client
socket to RequestHandler for further processing.
2. RequestHandler - Receives the request sent by the client, parses it,
process the parsed request to generate the response and send it back to
the server to sent the response to the client.

Obviously the design will be modified over time.
