I want to generate quizzes which are a different random subset of quiz items for each student

[Jeffrey Elkner]

I want to be able to create a quiz that consists of m possible items and have n (where n <= m) randomly selected for each student. So I may have a set of 20 items and tell pyquiz to pick 10 at random for each student. The probabliity would be very high that students would see different quiz from the students sitting next to them.
