  19  * Page to edit quizzes
  20  *
  21  * This page generally has two columns:
  22  * The right column lists all available questions in a chosen category and
  23  * allows them to be edited or more to be added. This column is only there if
  24  * the quiz does not already have student attempts
  25  * The left column lists all questions that have been added to the current quiz.
  26  * The lecturer can add questions from the right hand list to the quiz or remove them
  27  *
  28  * The script also processes a number of actions:
  29  * Actions affecting a quiz:
  30  * up and down  Changes the order of questions and page breaks
  31  * addquestion  Adds a single question to the quiz
  32  * add          Adds several selected questions to the quiz
  33  * addrandom    Adds a certain number of random questions to the quiz
  34  * repaginate   Re-paginates the quiz
  35  * delete       Removes a question from the quiz
  36  * savechanges  Saves the order and grades for questions in the quiz
