/*

OUTBOUND CODE v1-10

changes:
1-1 has taxes code
1-2 has canada taxes mod
1-3 has zero salefare replaced with regfare
1-4 fixed single digit day and month bug in- duh!
1-5 all zero fares are allowed, have already been entered into navitaire as 'free seats'
1-6 default 99p price mod
1-7 zero fare highlighting code, remove data from js into shtml file.
1-8 code for special route test added- see taxtables.js
1-9 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)
1-10 Tuned for new skylights 8 release - new link params
1-11 - added - expandDates: if true and no flights in date selected by user then use any dates availaible
1-12 - fixed if xml files are invalid - will continue without that route
1-13 - mod to handle new promo/discount codes 

multiple departing to single arrival
