Finished coding and testing SQLiteReservationsDAO

Oh okay I can explain. I put seat quantity in reservation so a user can reserve more than one seat on the Flight. The way I was thinking about it: A user is browsing through flights and decides he wants to reserve two first class seats. The reservation record will store how many seats, what class the seats belong to, and when the reservation is added to DB, RemainingFirstClass or Remaining Economy will be decremented by the appropriate amount. I don't know if putting that logic in here is a no-no.
