* Standalone HTML loading bar with only PHP and JS interface.

* The HTML_Progress2_Lite class allow you to add a quick

*
* Here is a basic example:
* <code>
* <html>
* <body>
* <?php
* require_once 'HTML/Progress2_Lite.php';
*
* function myProcess()
* {
* for ($i=0; $i<100000; $i++) { }

* $pbl->display();
*
* for($i=1; $i<=100; $i++) {
* $pbl->moveStep($i);
* myProcess();
