* sails.io.js
* ------------------------------------------------------------------------
* JavaScript Client (SDK) for communicating with Sails.
*
* Note that this script is completely optional, but it is handy if you're
* using WebSockets from the browser to talk to your Sails server.
*
* For tips and documentation, visit:
* http://sailsjs.org/#!documentation/reference/BrowserSDK/BrowserSDK.html
* ------------------------------------------------------------------------
*
* This file allows you to send and receive socket.io messages to & from Sails
* by simulating a REST client interface on top of socket.io. It models its API
* after the $.ajax pattern from jQuery you might already be familiar with.
*
* So if you're switching from using AJAX to sockets, instead of:
* `$.post( url, [data], [cb] )`
*
* You would use:
* `socket.post( url, [data], [cb] )`
