-- We are no likely to fail with an error when reading old BCF files, rather than just giving bad results
-- Added new class BCFVersion that consolidates all of the version management of BCF
-- Previous version would count all alt alleles as present in a sample, even if only 1 were present, because of the way VariantEval subsetted VCs
-- Updated code for subsetting VCs by sample to be clearer about how it handles rederiving alleles
-- Update a few pieces of code to get previous correct behavior
-- Updated a few MD5s as now ref calls at sites in dbSNP are counted as having a comp sites, and therefore show up in known sites when Novelty strat is on (which I think is correct)
-- Walkers that used old subsetting function with true are now using clearer version that does rederive alleles by default
-- Uses chi2 test for independences to determine if subcontext is worth representing. Give excellent visual results
-- Writes out analysis output file producing excellent results in R
-- Trivial reformatting of MathUtils
-- Reorganize functions in RecalDatum so that error rate can be computed indepentently. Added unit tests. Removed equals() method, which is a buggy without it's associated implementation for hashcode
-- New class RecalDatumTree based on QualIntervals that inherits from RecalDatum but includes the concept of sub data
-- VisualizeContextTree now uses RecalDatumTree and can trivially compute the penalty function for merging nodes, which it displays in the graph
-- Moved most of BQSR classes (which are used throughout the codebase) to utils.recalibration. It's better in my opinion to keep commonly used code in utils, and only specialized code in walkers. As code becomes embedded throughout GATK its should be refactored to live in utils
-- Removed unncessary imports of BQSR in VQSR v3
-- Now ready to refactor QualQuantizer and unit test into a subclass of RecalDatum, refactor unit tests into RecalDatum unit tests, and generalize into hierarchical recal datum that can be used in QualQuantizer and the analysis of adaptive context covariate
-- Update PluginManager to sort the plugins and interfaces. This allows us to have a deterministic order in which the plugin classes come back, which caused BQSR integration tests to temporarily change because I moved my classes around a bit.
-- Moved Datum, the now unnecessary superclass, into RecalDatum
-- Fixed some obviously dangerous synchronization errors in RecalDatum, though these may not have caused problems because they may not have been called in parallel mode
