*
* Usage: From "Joomla admin panel >> Module Manager >> under Module Advanced Parameters" assign a "Menu Tag ID" for your menu. Under "Module Parameters" set "Always show sub-menu Items" to "yes"
*
* Use the previous id as first argument for function accordionMenu()
*
* Example:
*
* insert following code in the head section of the template index.php
*
<script type="text/javascript">
window.addEvent('domready', function(){
accordionMenu(
   "mainmenu", // Menu Tag ID (this id is assigned to menu parent ul tag)
   "<?php echo $this->baseurl ?>/templates/<?php echo $this->template?>/images/expand.png", //path to image used to expand menu item
   "<?php echo $this->baseurl ?>/templates/<?php echo $this->template?>/images/collapse.png", //path to image used to collapse menu item
   {duration:400, transition:Fx.Transitions.Quart.easeOut}, // (optional argument) custom accordion options to override defaults, use null if you want to set next argument without changing this
   700 // (optional argument) hover delay in milliseconds over "parent menu item" to open its sublevels, default is 500
);
</script>

*
* Use CSS to style menu items for different levels
