Takes a genome file and (currently) a .vcf.gz or a .bed.gz and checks that:

* a .tbi is present * the VCF has ""##fileformat=VCF" as the first line * the VCF has a #CHROM header * the chromosome are in the order specified by the genome file (and present) * the positions are sorted * the positions are <= the chromosome lengths defined in the genome file.

As a result, any new genome going into GGD will have a .genome file that will dictate the sort order and presence or absence of the 'chr' prefix for chromosomes
