"""A class to display the a message explaining that the user has been banned.
We can ban a user for anti-social behavior. We indicate that the user is
banned by adding a 'banned' field to their User PB in the DB. Whenever
a user with a banned indicator visits any page, AssertBasePermission()
checks has_banned and redirects to this page.
