/*

OUTBOUND CODE v1-9

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)
