  * to the given course will be deleted.

  * database, it makes sense to remove all tracking as well (if stats databases exist)
  * so that a new course created with this code would not use the remains of an older
  * course.

  * @param string The code of the course to delete
  * @todo When deleting a virtual course: unsubscribe users from that virtual
  * course from the groups in the real course if they are not subscribed in
