/* tooltip-0.2.js - Small tooltip library on top of Prototype 
 * by Jonathan Weiss <jw@innerewut.de> distributed under the BSD license. 
 *
 * This tooltip library works in two modes. If it gets a valid DOM element 
 * or DOM id as an argument it uses this element as the tooltip. This 
 * element will be placed (and shown) near the mouse pointer when a trigger-
 * element is moused-over.
 * If it gets only a text as an argument instead of a DOM id or DOM element
 * it will create a div with the classname 'tooltip' that holds the given text.
 * This newly created div will be used as the tooltip. This is usefull if you 
 * want to use tooltip.js to create popups out of title attributes.
 * 
 *
 * Usage: 
 *   <script src="/javascripts/prototype.js" type="text/javascript"></script>
 *   <script src="/javascripts/tooltip.js" type="text/javascript"></script>
 *   <script type="text/javascript">
 *     // with valid DOM id
 *     var my_tooltip = new Tooltip('id_of_trigger_element', 'id_of_tooltip_to_show_element')
 *
 *     // with text
 *     var my_other_tooltip = new Tooltip('id_of_trigger_element', 'a nice description')
 *
 *     // create popups for each element with a title attribute
 *    Event.observe(window,"load",function() {
 *      $$("*").findAll(function(node){
 *        return node.getAttribute('title');
 *      }).each(function(node){
 *        new Tooltip(node,node.title);
 *        node.removeAttribute("title");
 *      });
 *    });
 *    
 *   </script>
 * 
 * Now whenever you trigger a mouseOver on the `trigger` element, the tooltip element will
 * be shown. On o mouseOut the tooltip disappears. 
 * 
 * Example:
 * 
 *   <script src="/javascripts/prototype.js" type="text/javascript"></script>
 *   <script src="/javascripts/scriptaculous.js" type="text/javascript"></script>
 *   <script src="/javascripts/tooltip.js" type="text/javascript"></script>
 *
 *   <div id='tooltip' style="display:none; margin: 5px; background-color: red;">
 *     Detail infos on product 1....<br />
 *   </div>
 *
 *   <div id='product_1'>
 *     This is product 1
 *   </div>
 *
 *   <script type="text/javascript">
 *     var my_tooltip = new Tooltip('product_1', 'tooltip')
 *   </script>
 *
 * You can use my_tooltip.destroy() to remove the event observers and thereby the tooltip.
