  19   * This file keeps track of upgrades to
  20   * the lesson module
  21   *
  22   * Sometimes, changes between versions involve
  23   * alterations to database structures and other
  24   * major things that may break installations.
  25   *
  26   * The upgrade function in this file will attempt
  27   * to perform all the necessary actions to upgrade
  28   * your older installation to the current version.
  29   *
  30   * If there's something it cannot do itself, it
  31   * will tell you what you need to do.
  32   *
  33   * The commands in here will all be database-neutral,
  34   * using the methods of database_manager class
  35   *
  36   * Please do not forget to use upgrade_set_timeout()
  37   * before any action that may take longer time to finish.
