Add example demonstrating a basic WebSocket protocol with message types

In HTML5 websockt or socket.io, you can consume messages just with the following lines of code:

```
var io = require('socket.io-client');
var socket = io('http://localhost:6001');

socket.on('connect', function () {
console.log('connected');
});

socket.on('StockTicker', function (data) {
console.log(data);
});

socket.on('StockBidAsk', function (data) {
console.log(data);
});

socket.on('Stock', function (data) {
console.log(data);
});
```

How to achieve the example above in this library?
