Updates and changes:
- Rewrite module handling conversion - it is now much faster than v2.0
- Minor changes to heterozygous genotype reporting by the concordance module, related to the bug below
Bug fixes:
- A minor inconsistency in how heterozygous genotypes are read and written (AB versus BA) led to the concordance module reporting a category of "reversed heterozygous" SNPs in the statistics file. This is now fixed and the number of heterozygous concordant SNPs are reported on a single line
