a) Turns out previous change of centering haplotype around indel was a bad idea. Context to the left of indel is important but not as important as right one, because by definition all alleles start at the same location, so haplotype is the same to the left of indel regardless of allele. So, go back to having a constant size window to the left of event.
b) Expand reference context so we can test larger haplotypes.
c) Optimize computation of read likelihoods by doing them in linear array instead of in a matrix - no difference in biallelic sites but could be significantly faster in multiallelic sites.
d) Bug fix: read alignment wasn't being computed correctly if, a) we were at an insertion, b) read started right at the insertion, c) read CIGAR didn't include insertion - more of these corner conditions are lurking, so a revamped computation of how reads align to candidate haplotypes is in the works.
e) Add debug option not to use prior haplotype likelihoods.
f) Don't hard-code NA12878 for genotyping, now sample name is a required input argument.
g) Bug fix: if there are no reads covering a candidate indel event, just output NO_CALL (didn't notice this in HiSeq, but in P1 data it happens all the time). I need to add a confidence threshold for calling later on.
