 * Usage:
 *  
 *  jQuery(document).ready(function($) {
 *    $('a[rel*=facebox]').facebox() 
 *  })
 *
 *  <a href="#terms" rel="facebox">Terms</a>
 *    Loads the #terms div in the box
 *
 *  <a href="terms.html" rel="facebox">Terms</a>
 *    Loads the terms.html page in the box
 *
 *  <a href="terms.png" rel="facebox">Terms</a>
 *    Loads the terms.png image in the box
 *
 *
 *  You can also use it programmatically:
 * 
 *    jQuery.facebox('some html')
 *
 *  This will open a facebox with "some html" as the content.
 *    
 *    jQuery.facebox(function($) { $.ajaxes() })
 *
 *  This will show a loading screen before the passed function is called,
 *  allowing for a better ajax experience.
