-- If eval has genotypes and comp has genotypes, then subset the genotypes of comp down to the samples being evaluated when considering TP, FP, FN, TN status. This is important in the case where you want to use this to assess, for example, the quality of calls on NA12878 but you have a CEU trio comp VCF. The previous version was counting sites polymorphic in mom against the calls in NA12878.
-- Added testdata VCF and integrationtests to ensure this behavior continues in the future
-- TODO: actually run integration tests when I have an internet connection
