Add a full screen mode.
In order to ban users from using navigation buttons of their navigator, a full screen mode should be developed.
This full screen mode will be accessible from the Identification page : once the user has clicked on the "Sign in" button, the homepage of the Dynamic COMPAS will be opened in a new popup without navigation buttons and address bar, while the Identification page will be switched to a new page which informed that a Dynamic COMPAS session is opened for the given user, and that it is possible to reopen the homepage of this session by clicking on a link (which reopens the popup).
