-Moved some of the more specialized / complex VariantContext and VCF utility
methods back to the GATK.
-Due to this re-shuffling, was able to return things like the Pair class back
to the GATK as well.
1) Better documentation on the meta data file for VariantsToBinaryPed with examples of each file type
2) MannWhitneyU can now take an argument on creation to turn off dithering. This pertains to JIRA-GSA-571 but does not fix it,
as it isn't hooked up to the command line. Next step is to add an argument to the command line where it's accessible to the
annotation classes (e.g. from either UG or the VariantAnnotator).
3) Added some dumb python scripts to deal with Plink files, and a script to convert plink binaries to VCF to help sanity check. Basically if you want to do an analysis on genotype data stored in plink binary format, your choices are:
1) Add a new module to Plink [difficulty rating: Impossible -- code obfuscation]
2) Steal plink parsing code from software (Plink/PlinkSeq/GCTA/Emacks/etc) that readds the files [difficulty rating: Oppressive -- code not modularized at all)
3) Write your own dumb stuff [difficutly rating: Annoying]
What's been added is the result of 3. It's a library so nobody else has to do this, so long as they're comfortable with python.
