/**
* This behaves like a WebSocket in every way, except if it fails to connect,
* or it gets disconnected, it will repeatedly poll until it successfully connects
* again.
*
* It is API compatible, so when you have:
* ws = new WebSocket('ws://....');
* you can replace with:
* ws = new ReconnectingWebSocket('ws://....');
*
* The event stream will typically look like:
* onconnecting
* onopen
* onmessage
* onmessage
* onclose // lost connection
* onconnecting
* onopen // sometime later...
* onmessage
* onmessage
* etc...
*
* It is API compatible with the standard WebSocket API, apart from the following members:
*
* - `bufferedAmount`
* - `extensions`
* - `binaryType`
*
* Latest version: https://github.com/joewalnes/reconnecting-websocket/
* - Joe Walnes
*
* Syntax
* ======
* var socket = new ReconnectingWebSocket(url, protocols, options);
*
* Parameters
* ==========
* url - The url you are connecting to.
* protocols - Optional string or array of protocols.
* options - See below
*
* Options
* =======
* Options can either be passed upon instantiation or set after instantiation:
*
* var socket = new ReconnectingWebSocket(url, null, { debug: true, reconnectInterval: 4000 });
*
* or
*
* var socket = new ReconnectingWebSocket(url);
* socket.debug = true;
* socket.reconnectInterval = 4000;
*
* debug
* - Whether this instance should log debug messages. Accepts true or false. Default: false.
*
* automaticOpen
* - Whether or not the websocket should attempt to connect immediately upon instantiation. The socket can be manually opened or closed at any time using ws.open() and ws.close().
*
* reconnectInterval
* - The number of milliseconds to delay before attempting to reconnect. Accepts integer. Default: 1000.
*
* maxReconnectInterval
* - The maximum number of milliseconds to delay a reconnection attempt. Accepts integer. Default: 30000.
*
* reconnectDecay
* - The rate of increase of the reconnect delay. Allows reconnect attempts to back off when problems persist. Accepts integer or float. Default: 1.5.
*
* timeoutInterval
* - The maximum time in milliseconds to wait for a connection to succeed before closing and retrying. Accepts integer. Default: 2000.
*
