 * Version: 0.2.0
 * Requires Jquery 1.2.1 from version 0.2.0 onwards. 
 * For jquery 1.1.x, use version 0.1.0 of lavalamp
 */

/**
 * 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.
