*   This program s sets up a flight database according to the file
*   the user supplies. It takes seven parameters for each flight.
*   Flight Number, Departure Location, Arrival Location, Departure
*   Time, Arrival Time, Departure Date and Price, in that order.
*   It then allows several manipulations, such as cancelling a flight
*   from the database, adding more flights to the data base, updating
*   flight info by reading in a file with the most current information,
*   creating reservations and displaying all those that match from the
*   current database and sorting them by price, which you can then 
*   select the flight desired. There is also a quit function so you
*   can get out of this wonderful program.
