/*
* 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')
*    jQuery.facebox('some html', 'my-groovy-style')
*
*  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, an image, or the contents of a div:
*
*    jQuery.facebox({ ajax: 'remote.html' })
*    jQuery.facebox({ ajax: 'remote.html' }, 'my-groovy-style')
*    jQuery.facebox({ image: 'stairs.jpg' })
*    jQuery.facebox({ image: 'stairs.jpg' }, 'my-groovy-style')
*    jQuery.facebox({ div: '#box' })
*    jQuery.facebox({ div: '#box' }, 'my-groovy-style')
*
*  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
*    afterClose.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... })
*
