// destination_seatseeker_v1-5
/*

1-2	all zero fares are allowed, have already been entered into navitaire as 'free seats'
1-3	added 99p by default code
1-4 	 mod for new tax element in xml feed - essentially 1-8 code removed and new flight object tax element added, removed saleFareToggle code,
	 use a comparason instead and go with the cheapest, now that AdultSaleFares return as null if not present (not 0.00)
1-5	For Skylights 8 - New URl code, new error trapping,
1-6 removed tax toggle stuff as taxes are now included in prices by default
