/**
 * sails.io.js
 * v1.1.13
 * ------------------------------------------------------------------------
 * 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.com/documentation/reference/web-sockets/socket-client
 * ------------------------------------------------------------------------
 *
 * 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] )`
