/**

 * Page to edit quizzes

 *

 * This page generally has two columns:

 * The right column lists all available questions in a chosen category and

 * allows them to be edited or more to be added. This column is only there if

 * the quiz does not already have student attempts

 * The left column lists all questions that have been added to the current quiz.

 * The lecturer can add questions from the right hand list to the quiz or remove them

 *

 * The script also processes a number of actions:

 * Actions affecting a quiz:

 * up and down  Changes the order of questions and page breaks

 * addquestion  Adds a single question to the quiz

 * add          Adds several selected questions to the quiz

 * addrandom    Adds a certain number of random questions to the quiz

 * repaginate   Re-paginates the quiz

 * delete       Removes a question from the quiz

 * savechanges  Saves the order and grades for questions in the quiz
