+/* tooltip-0.2.js - Small tooltip library on top of Prototype 
+ * by Jonathan Weiss <jw@xxxxxxxxxxxx> 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.
