historyListeners
Simple History management class for back/forward button support.
This class allows your AJAX application to use a history. Each time
you call newItem(), a new item is added to the history and the history
listeners are notified. If the user clicks the browser's forward or back
buttons, the appropriate item (a string passed to newItem) is fetched
from the history and the history listeners are notified.
The address bar of the browser contains the current token, using the
"#" seperator (for implementation reasons, not because we love
the # mark).
You may want to check whether the hash already contains a history
token when the page loads and use that to show appropriate content; this
allows users of the site to store direct links in their bookmarks or send
them in emails.
To make this work properly in all browsers, you must add a specially
named iframe to your html page, like this:
<iframe id='__pygwt_historyFrame' style='width:0;height:0;border:0'
/>
