OK, it seems reliable enough now for alpha testing.

If you have existing quizzes, delete them all, then
drop all the quiz tables and delete the quiz line from
the modules table.

Things to do still:

  - add/edit/remove categories
  - display question feedback on submissions ...
  - record the time they started the quiz, as well as the completion.
  - place time limits between attempts
  - add full specification of quiz open time and quiz close time
