*
* 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')
*
*  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.
