This functions calculates the value of the expected heterozygosity for each SNP.
Expected_Het(Pop_Pi)if the input is a single matrix, the output will be a matrix where each row represents a different population and each column is the expected heterozygosity of a population at that site. If the input is a list, the output will also be a list, with each entry corresponding to a different locus. Each of those entries will be a matrix with different populations in different rows and the expected heterozygosity of different sites at different columns.
is a matrix or list of allele frequencies. When dealing with a single locus, this input is a matrix and when dealing with multiple loci it is a list. Each entry of that list is a matrix representing a different locus. Each row of that matrix should correspond to a different population and each column to a different SNP.
