/** Trivial demo for the bck2brwsr project. First of all start

 * with <a href="TestPage.html">your XHTML page</a>. Include there

 * a script that will <em>boot Java</em> in your browser.

 * <p>

 * Then use <code>@Page</code> annotation to 

 * generate a Java representation of elements with IDs in that page.

 * Depending on the type of the elements, they will have different 

 * methods (e.g. <code>PG_TITLE</code> has <code>setText</code>, etc.).

 * Use <code>@OnClick</code> annotation to associate behavior

 * with existing elements. Use the generated elements

 * (<code>PG_TITLE</code>, <code>PG_TEXT</code>) to modify the page.

 * <p>

 * Everything is type-safe. As soon as somebody modifies the page and

 * removes the IDs or re-assigns them to wrong elements. Java compiler

 * will emit an error.

 * <p>

 * Welcome to the type-safe HTML5 world!
