48 : * @brief Something on a lane to be noticed about vehicle movement
49 : *
50 : * Base class of all move-reminders. During move, the vehicles call

53 : * positioned at during insertion or lanechange notifyEnter() is
54 : * called. If a vehicle leaves the reminder lane it calls notifyLeave().
55 : *
56 : * The reminder knows whom to tell about move, insertion and lanechange. The
57 : * vehicles will remove the reminder that is not notifyMove() from
58 : * their reminder container.
59 : *
