/**
 * This is a project designed to get around sites using Cloudflare's "I'm under attack" mode.
 * Using the PhantomJS headless browser, it queries a site given to it as the second parameter,
 *  waits six seconds and returns the cookies required to continue using this site.  With this, 
 *  it is possible to automate scrapers or spiders that would otherwise be thwarted by Cloudflare's 
 *  anti-bot protection.
 * 
 * To run this: phantomjs cloudflare-challenge.js http://www.example.org/
