a) Scrapped the way in which we constructed candidate haplotypes because it wasnt fully correct and yielded corner conditions with incorrect genotyping and likelihood computation. Ideally, a haplotype should "cover" the read and the most likely alignments should be such that the ends of the read are inside the ends of the haplotype. This wasn't happening, and if you have a "dangling read off a haplotype" the probabilistic alignment model may prefer to shift a read instead of scoring it correctly - this is especially bad with tandem repeat insertions.
So now, we build haplotypes based on the reference context and adaptively change them based on read alignment positions, plus some padding and uncertainty in the alignment.
b) Changed the way soft clipped based are dealt with. Instead of either ignoring them or using them, we only use them if the read start or end position (after soft clipping) are within eventDistance of the current location. This is done because it's very common that BWA's strictly local SW implementation will soft clip every single read at an insertion position because it couldn't place that end of the read without too many mismatches, but the read is legit and the bases are good quality. If we don't take these bases into consideration, reads which are informative of an insertion event are essentially discarded because the informative part is clipped away.
c) Several cleanups and fixes to the context-dependent gap penalty model based on length of HRun.

indexes'. Not yet elegant, but proves that it circumvents the performance
issues associated with the meta-index.

IndelUtils: added a isInsideExtendedIndel() method to filter the above mentioned.

VariantEval: now sports the new MendelianViolation utility class.
MendelianViolationClassifier: I noticed I had broken chartl's walker by changing VariantEval, so I took the liberty to modify it to use the new library too, though I kept modifications to a minimum, could have gone into full integration if this is a useful tool, but since it's in oneoffs, I decided not to go all out.
MendelianViolation: Some getter methods were added for chartl and VariantEval.

b) small bug fix when setting debug arguments

ps: I moved it out of tribble. If you think it should reside in a different place, just yell at me.

Reinstated. Proper unit test to follow.

b) Add an experimental annotation to log indel type string inside the INFO field, just for debugging/temp analysis purposes (will consider making it standard if it proves useful).

given an annotated VCF and a BAM file, it genotypes (using the reads in the BAM) each variant in the VCF (for snp or indel) and validates (or not) the 'known' annotation. Outputs a truth table with the PPV and NPV values, and optionally a vcf file with the variants that had enough coverage to be validated. You can optionally provide a minimum depth of coverage and only do the analysis conditional on that. (will write a wiki for this walker, as it might be useful for future validation essays).

- Don't know how I got the wiggle header so utterly wrong. Fixed.
- Q-values now have a static maximum of 2000 so IGV averaging won't make everything look spikey and ugly.
- Changing windows to size 100 for (hopefully) better resolution.

- Basic
- Multiple technology
- Test minIndelCnt parameter
Added also 2 disabled tests:
- Parallelization: issue w/code right now is that if -nt > 1, filter field shows "PASS" instead to ".", cause TBD
- Genotype given alleles mode: code not working yet.
