Acknowledge plagiarism statement access rule
If you install this plugin, there is a new option on the quiz settings form, and
if the teacher turns that on, then when a student tries to start a quiz attempt,
they will see a statement about plagiarism and cheating, and they will have to
agree that they will be good before they are allowed to start the quiz attempt.
This quiz access rule was created by Tim Hunt at the Open University. It can be
used with versions 2.2 of Moodle, or later.
