/**
	Bullet is a client-side javascript library AND server-side Cowboy handler
	to manage continuous streaming. It selects the proper transport in a fully
	automated way and makes sure to always reconnect to the server on any
	disconnect. You only need to handle sending messages, receiving them,
	and managing the heartbeat of the stream.

	Usage: $.bullet(url);

	Then you can register one of the 4 event handlers:
	onopen, onmessage, onclose, onheartbeat.

	onopen is called once right after starting the bullet stream.
	onmessage is called once for each message receveid.
	onclose is called once right after you voluntarily close the socket.
	onheartbeat is called once every few seconds to allow you to easily setup
	a ping/pong mechanism.
