 /**
  * Delete a course

  * given course is a virtual course, the database and directory will not be
  * deleted.
  * When the given course is a real course, also all virtual courses refering
  * to the given course will be deleted.
  * Considering the fact that we remove all traces of the course in the main
  * 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
  * that real course.
  * @todo Remove globals
