/* 
Simple JQuery Accordion menu.
HTML structure to use:

Notes: 

1: each menu MUST have an ID set. It doesn't matter what this ID is as long as it's there.
2: each menu MUST have a class 'menu' set. If the menu doesn't have this, the JS won't make it dynamic

Optional extra classnames:

noaccordion : no accordion functionality
collapsible : menu works like an accordion but can be fully collapsed
expandfirst : first menu item expanded at page load

<ul id="menu1" class="menu [optional class] [optional class]">
<li><a href="#">Sub menu heading</a>
<ul>
<li><a href="http://site.com/">Link</a></li>
<li><a href="http://site.com/">Link</a></li>
<li><a href="http://site.com/">Link</a></li>
...
...
</ul>
<li><a href="#">Sub menu heading</a>
<ul>
<li><a href="http://site.com/">Link</a></li>
<li><a href="http://site.com/">Link</a></li>
<li><a href="http://site.com/">Link</a></li>
...

</ul>

// Jquery lightbox


/**
 * jQuery Lightbox
 * Version 0.5 - 11/29/2007
 * @author Warren Krewenki
 *
 * Changes by:
 * @author Krzysztof Kotowicz <koto at webworkers dot pl>:
 *  - bugfix: multiple instances of Lightbox galleries allowed
 *    (using opts variable instead of $.fn.lightbox.defaults)
 *  - bugfix: use var for local variables in a few functions
 *  - added support for navbarOnTop setting
 *  - added support for displayTitle setting
 *  - added support for slideNavBar setting (with slideNavBarSpeed)
 *  - added support for displayHelp setting
 *  - added support for fitToScreen setting (ported Lightbox VinDSL hack)
 *    (see http://www.huddletogether.com/forum/comments.php?DiscussionID=307)
 *  - plugin now uses jQuery.width() and jQuery.height()
 *  - removed eval() calls
 *  - removed destroyElement - uses jQuery.remove()
 *  - use of prevLinkText, nextLinkText and help
 *  - all strings are now placed in opts.strings to allow for customization/translation
 *
 * Based on Lightbox 2 by Lokesh Dhakar (http://www.huddletogether.com/projects/lightbox2/)
 * Originally written to make use of the Prototype framework, and Script.acalo.us, now altered to use jQuery.
