+ * 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... })
+ *
