rpoplin a8d37da10b Checking in everyone's changes to the variant recalibrator. We now calculate the variant quality score as a LOD score between the true and false hypothesis. Allele Count prior is changed to be (1 - 0.5^ac). Known prior breaks out HapMap sites

ebanks c6ad26e04f 1) When quals/GQs are really integers (x.00), strip off the floating points.
2) Keep track of whether vcf records are unfiltered vs. pass filters in the variant context so we can regenerate the records on output.
3) No more "ID" hard-coded all over the code to set the VariantContext ID.  Use a static variable instead.

delangel 55b756f1cc First step in major cleanup/redo of VCF functionality. Specifically, now:
a) VCF track name can work again with 3.3 or 4.0 VCF's when specifying -B name,VCF,file. Code will read header and parse automatically the version. 
b) Old VCF codec is deprecated. Reader goes now direct from parsing VCF lines into producing VariantContext objects, with no intermediate VCF records. If anyone can't resist the urge to still input files using the old method, a new VCF3Codec is in place with the old code, but it will be eventually deleted.
c) VCF headers and VCF info fields no longer keep track of the version. They are parsed into an internal representation and will be output only in VCF4.0 format.
d) As a consequence, the existing GATK bug where files are produced with VCF4 body but VCF3.3 headers is solved.
e) Several VCF 4.0 writer bugs are now solved.
f) Integration test MD5's are changed, mostly because of corrected VCF4.0 headers and because validation data mostly uses now VCF4.0.
g) Several VCF files in the ValidationData/ directory have been converted to VCF 4.0 format. I kept the old versions, and the new versions have a .vcf4 extension.

Pending issues:
a) We are still not dealing with indels consistently or correctly when representing them. This will be a second part of the changes.
b) The VCF writer doesn't use VCFRecord but it does still use a lot of leftovers like VCFGenotypeEncoding, VCFGenotypeRecord, etc. This needs to be simplified and cleaned.

ebanks 6b5c88d4d6 The GATK no longer writes vcf3.3; welcome to the world of vcf4.0. Needed to fix a few output bugs to get this to work, but it's looking great. Much more still to come. Guillermo: hopefully this doesn't break your local build too badly.

rpoplin 255b036fb5 Variant Recalibrator MLE EM algorithm is moved over to variational Bayes EM in order to eliminate problems with singularities when clustering in higher than two dimensions. Because of this there is no longer a number of Gaussians parameter. Wiki will be updated shortly with new recommended command.

rpoplin 724affc3cc Major bug fixes for the Variant Recalibrator. Covariance matrix values are now allowed to be negative. When probabilities are multiplied together the calculation is done in log space, normalized, then converted back to real valued probabilities. Clustering weights have been changed to only use HapMap and by-1000genomes sites. The -nI argument was removed and now clustering simply runs until convergence. Test cases seem to work best when using just two annotations (QD and SB). More changes are in the works and are being evaluated. Misc fixes to walkers that use RScript due to CentOS changes.

aaron b978d5946b adding changes for VCF 4, mostly in the way we handle VCF headers. The header fields are now aware of the differences between different VCF formats. There was also a bunch of clean-up of out-of-spec VCF used in the tests (mismatched VCF file format fields, etc), and updates to the associated integration tests. Also some logging statements for BTI.

rpoplin 2014837f8a VariantOptimizer package is moved to core, renamed as VariantRecalibration, and added to the binary release package. VariantOptimizer walker is renamed to GenerateVariantClustersWalker and ApplyVariantClustersWalker renamed to VariantRecalibrator. Integration tests added, performance tests still to be done.
