-- New approach to making VariantContexts modeled on StringBuilder
-- No more modify routines -- use VariantContextBuilder
-- Renamed isPolymorphic to isPolymorphicInSamples. Same for mono
-- getChromosomeCount -> getCalledChrCount
-- Walkers changed to use new VariantContext. Some deprecated new VariantContext calls remain
-- VCFCodec now uses optimized cached information to create GenotypesContext.
-- Major change to how chromosomeCounts is computed. Now NO_CALL alleles are always excluded. So ChromosomeCounts(A/.) is 1, the previous result would have been 2.
-- Naming changes for getSamplesNameInOrder()
-- Now these routines all iterate in sample name order (genotypes.iterateInSampleNameOrder) so that the results of UG and the annotator do not depend on the particular order of samples we see for the exact model and the RankSumTest
-- Compares performance across a bunch of common operations with GATK 1.3 version of VariantContext and GATK 1.4
-- 1.3 VC and associated utilities copied wholesale into test directory under v13
compressed the representation of the reduce reads counts by offset results in 17% average compression in final BAM file size.
Example compression -->
from : 10, 10, 11, 11, 12, 12, 12, 11, 10
to: 10, 0, 1, 1,2, 2, 2, 1, 0
-- I have no idea why I named this InferredGeneticContext, a totally meaningless term
-- Renamed to CommonInfo.
-- Made package protected, as no one should use this outside of VariantContext and Genotype
-- UGEngine was using IGC constant, but it's now using the public one in VariantContext.
-- Enables further sophisticated optimizations, as this class can be smarter about storing the data and will directly support operations like subset to samples
-- All instances in the gatk that used Map<String, Genotype> now use GenotypeMap type.
-- Amazingly, there were many places where HashMap<String, Genotype> is used, so that the order of the genotypes is technically undefined and could be dangerous. Now everything uses GenotypeMap with a specific ordering of samples (by name)
-- Integrationtests updated and all pass
-- This is a more convenient accesssor than subContextOfGenotypes, represents nearly all of the use cases of the former function, and potentially can be implemented more efficiently.
