-- Old version converted doubles directly from strings. New version uses VariantContext getAttributeAsDouble() that looks at the values directly to determine how to convert from Object to Double (via Double.valueOf, (Double), or (Double)(Integer)).
-- getAttributeAsDouble() is now smart in converting integers to doubles as needed
-- Removed unnecessary logging info in BCF2Codec
-- Added integration tests to ensure that VQSR works end-to-end with BCF2 using sites version of the file khalid sent to me
-- Added vqsr.bcf_test.snps.unfiltered.bcf file for this integration test
-- Added bonferroni corrected p-value pruning, so you tell it how significant of a different you are willing to collapse in the tree, and it prunes the tree down to this maximum threshold
-- Penalty is now a phred-scaled p-value not the raw chi2 value
-- Split command line arguments in VisualizeContextTree into separate arguments for each type of pruning
-- Basically I was treating the context history in the wrong direction, effectively predicting the further bases in the context based on the closer one. Totally backward. Updated the code to build the tree in the right direction.
-- Added a few more useful outputs for analysis (minPenalty and maxPenalty)
-- Misc. cleanup of the code
-- Overall I'm not 100% certain this is even the right way to think about the problem. Clearly this is producing a reasonable output but the sum of chi2 values over the entire tree is just enormous. Perhaps a MCMC convergence / sampling criterion would be a better way to think about this problem?
-- Better output file name defaults
-- Fixed nasty bug where I included non-existant quals in the contexts to process because they showed up in the Cycle covariate
-- Data is processed in qual order now, so it's easier to see progress
-- Logger messages explaining where we are in the process
-- When in UPDATE mode we still write out the information for an equivalent prune by depth for post analysis
-- VisualizeContextTree now can write out an equivalent BQSR table determined after adaptive context merging of all RG x QUAL x CONTEXT trees
-- Docs, algorithm descriptions, etc so that it makes sense what's going on
-- VisualizeContextTree should really be simplified when into a single tool that just visualize the trees when / if we decide to make adaptive contexts standard part of BQSR
-- Misc. cleaning, organization of the code (recalibation tests were in private but corresponding actual files were public)
-- 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
