-- Updating integration tests, confirming that results for the original EXACT model are as expected given our new more rigorous application of likelihoods, priors, and posteriors
-- Fix basic logic bug in AFCalcResult.isPolymorphic and UnifiedGenotypeEngine, where isNonRef really meant isRef. Not ideal. Finally caught by some tests, but good god it almost made it into the code
-- Now takes the Math.abs of the phred-scaled confidence so that we don't see -0.0
-- Massive new suite of unit tests to ensure that bi-allelic and tri-allele events are called properly with all models, and that the IndependentAllelesDiploidExactAFCalc calls events with up to 4 alt alleles correctly. ID'd some of the bugs below
-- Fix sort order bug in IndependentAllelesDiploidExactAFCalc caught by new unit tests
-- Fix bug in GeneralPloidyExactAFCalc where the AFCalcResult has meaningless values in the likelihoods when no there we no informative GLs.
