iframe - ing the facebook dialog display

There is at least 3 kind of display for the facebook dialog:

• page. the dialog will display with facebook header and footer taking all area of the page.
• popup. the dialog rendered in a window.
• iframe. we can render the dialog in an iframe element.

For the last display mode, we cannot find anywhere in the documentation, a good example. But, i think we can do this.

First as the documentation said, iframe display mode require an access_token. You must have this code in hand.
