* calculates and interprets the coverage of a given interval track
* allows to expand intervals by specified number of bases
* classifies targets as CALLABLE, LOW_COVERAGE, EXCESSIVE_COVERAGE and POOR_QUALITY.
* outputs text file for now (testing purposes only), soon to be VCF.
* filters are overly aggressive for now.
* Knuth-shuffle is a simple, yet effective array permutator (hope this is good english).
* added a simple randomSubset that returns a random subset without repeats of any given array with the same probability for every permutation.
* added unit tests to both functions
Bases that were excluded for MQ and BQ filters are now contributing to the MQ RMS (but not to consensus base counts and variant/not variant region triggers).
b) Added (but left commented out since it may affect integration tests and to isolate commits) fix to per-sample DP reporting, so that deletions are included in count.
c) Bug fix to avoid having non-reference genotypes assigned to samples with PL=0,0,0. Correct behavior should be to no-call these samples, and to ignore these samples when computing AC distribution since their likelihoods are not informative.
It is outputting a VCF with the 'second best guess' for the alternate allele correctly. Annotations are added at the pool level, but may get overwritten at the lane and site level. Still need to implement the merging of the the annotations at higher levels.
Calls are now made based on the likelihood AC model. Two filters are applied: minQual and minPower. Output is now a VCF file with the variant context. It's now called the gatk's PoolCaller, no longer Replication Validation framework. Lots of testing ensue....
