• simplified json request and response.
• Simplified heartbeat message and response. ping pong happens every 10 secs.
• doesnt kill the session for subscribing and unsubscribing tokens.
• if the client sends an unsubs request for the tokens which are not subscribed then the system will gracefully ignore the request without impacting the feed for currently subscribed tokens.
• implemented a max of 1000 active connections per session.

TODO:

• testing for failure of subscribtions. (basic validator is present)
• extensive error handling
• more clarity and testing about the 1000 active connections.
