Merged repo:

• sahilrajput03/web-rtc into OLDER_STUFF directory.

Connection Initiation:

• When client sends a request to server for websocket connection, server responds with 101 HTTP response and the handshake is complete.
• At this point tcp/ip connection is left open allowing bi-directional messaging to be done with very low latency.
• The connection is left open until one of the parties is left off.
• Its also known as full-duplex connection in telecommunication terms that means both parties can talk at the same time.
