627 * requests. It is responsible for concatenation of time intervals and position

630 *
631 * - Events Requests Servicing Algorithm
632 *
633 * Data structures necessary :
634 *
635 * List of requests added to context : list_in
636 * List of requests not added to context : list_out
637 *
638 * Initial state :
639 *
640 * list_in : empty
641 * list_out : many events requests
642 *
643 * FIXME : insert rest of algorithm here
