/*
Universal Cookie Cutter
Version 2.1b
Created to streamline cross-brand A/B testing
New version modularizes variables

instantiate new object:

MyCookieCutter = new universalCookieCutter([CookieVarName],      // name of your cookie variable
[CookieUsedName],     // name of cookie used (usually 'mktUniversalPersist')
[CookieValueBase],    // name of base cookie value so AB tests can be distinguished (ONOctFSEG)
[ForcedModeBaseName], // distinct base string for forced mode, (oldnavyabmode), etc
[SegmentBreakdown]    // segment breakdowns separated by "-" (80-10-10) highest to lowest values
[eVar you are using]  // right now it is either s_eVar24 or s.eVar36 - enter either "24" or "36"
[Piperlime-only segment] // Piperlime often doesn't segment, scan for this variable and overwrite it. 
);
A sample instantiation:

ONBRABCookieCutter = new universalCookieCutter("ONBRAB","mktUniversalPersist","ONBRDecXSEG","onbrabmode","70-10-10-5-5","24","0625FSSegE");
