Feature #3710 (vcfTabix UI options): Added controls for selection of centervariant for haplotype clustering/sorting.  Also, some hgc improvements:
made the Genotype Details table into a collapsible section; better display
of QUAL and FILTER column values, which also involved improving the
representation of those columns in src/inc/vcf.h.
