/* 
Simple JQuery 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>

</ul>
