/**************************************************************************
 * ScheduledFlight is a class that is used by FlightGear's Traffic Manager
 * A scheduled flight can be assigned to a schedule, which can be assigned 
 * to an aircraft. The traffic manager decides for each schedule which
 * scheduled flight (if any) is currently active. I no scheduled flights
 * are found active, it tries to position the aircraft associated with this
 * schedule at departure airport of the next scheduled flight.
 * The class ScheduledFlight is a software implimentation of this.
 * In summary, this class stores arrival and departure information, as well
 * as some administrative data, such as the callsign of this particular
 * flight (used in future ATC scenarios), under which flight rules the 
 * flight is taking place, as well as a requested initial cruise altitude.
 * Finally, the class contains a repeat period, wich indicates after how
 * many seconds a flight should repeat in this schedule (which is usually
 * after either a day or a week). If this value is zero, this flight won't
 * repeat.
