   * takes care that the view (the interface) can give its functionality with
   * low computational complexity.
   *
   * Here, it contains multiple LinkedCell_Model instances, each with different
   * edge lengths of the inherent mesh. You request a LinkedCell instance from
   * the controller, but you basically just receive a const interface reference
   * to a present LinkedCell instance.
