  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
