  Calculates basic population statistics at bi-allelic sites. The allele frequency is the number of non-reference alleles divided by the total number of alleles.  The expected hetrozygosity is 2*p*q, where p is the non-reference allele frequency and q is 1-p.  The observed heterozgosity is the fraction of 0/1 genotypes out of all genotypes.  The inbreeding coefficient, Fis, is the relative heterozygosity of each individual vs. compared to the target group.

     3. target allele frequency      
     4. expected heterozygosity      
     5. observed heterozygosity      
     6. number of hets               
     7. number of homozygous ref     
     8. number of homozygous alt     
     9. target Fis
