/*
 * Facebox (for jQuery)
 * version: 1.2 (05/05/2008)
 * @requires jQuery v1.2 or later
 *
 * Examples at http://famspam.com/facebox/
 *
 * Licensed under the MIT:
 *   http://www.opensource.org/licenses/mit-license.php
 *
 * Copyright 2007, 2008 Chris Wanstrath [ chris@ozmm.org ]
 *
 * Usage:
 *  
 *  jQuery(document).ready(function() {
 *    jQuery('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')
 *
 *  The above will open a facebox with "some html" as the content.
 *    
 *    jQuery.facebox(function($) { 
 *      $.get('blah.html', function(data) { $.facebox(data) })
 *    })
 *
 *  The above will show a loading screen before the passed function is called,
 *  allowing for a better ajaxy experience.
 *
 *  The facebox function can also display an ajax page or image:
 *  
 *    jQuery.facebox({ ajax: 'remote.html' })
 *    jQuery.facebox({ image: 'dude.jpg' })
 *
 *  Want to close the facebox?  Trigger the 'close.facebox' document event:
 *
 *    jQuery(document).trigger('close.facebox')
 *
 *  Facebox also has a bunch of other hooks:
 *
 *    loading.facebox
 *    beforeReveal.facebox
 *    reveal.facebox (aliased as 'afterReveal.facebox')
 *    init.facebox
 *
 *  Simply bind a function to any of these hooks:
 *
 *   $(document).bind('reveal.facebox', function() { ...stuff to do after the facebox and contents are revealed... })
 *
