 *


 * 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.
