/**
* Creates a menu with an unordered list of menu-items. You can either use the CSS that comes with the plugin, or write your own styles
* to create a personalized effect
*
* The HTML markup used to build the menu can be as simple as...
*
* <ul class="lavaLamp">
* <li><a href="#">Home</a></li>
* <li><a href="#">Plant a tree</a></li>
* <li><a href="#">Travel</a></li>
* <li><a href="#">Ride an elephant</a></li>
* </ul>
*
* Once you have included the style sheet that comes with the plugin, you will have to include
* a reference to jquery library, easing plugin(optional) and the lavaLamp(this) plugin.
*
* Use the following snippet to initialize the menu.
* $(function() { $(".lavaLamp").lavaLamp({ fx: "backout", speed: 700}) });
*
* Thats it. Now you should have a working lavaLamp menu.
*
* @param an options object - You can specify all the options shown below as an options object param.
*
* @option fx - default is "linear"
* @example
* $(".lavaLamp").lavaLamp({ fx: "backout" });
* @desc Creates a menu with "backout" easing effect. You need to include the easing plugin for this to work.
*
* @option speed - default is 500 ms
* @example
* $(".lavaLamp").lavaLamp({ speed: 500 });
* @desc Creates a menu with an animation speed of 500 ms.
*
* @option click - no defaults
* @example
* $(".lavaLamp").lavaLamp({ click: function(event, menuItem) { return false; } });
* @desc You can supply a callback to be executed when the menu item is clicked.
* The event object and the menu-item that was clicked will be passed in as arguments.
