Simple chat application example about using Sails Websocket.

This is simple chat application example about using Sails Websocket (pubsub). I also included  README how to get started with simple instructions. Later I will provide step by step explanation about Sails's pubsub with detail instruction.

Let me know if I must change something.

If anyone want to help with explanation, it's very welcome. I'm not good at english yet :laughing: 

Keep up the good works Guys.
I Love Sails :+1:
