Improve calculation of genetic and allelic parameters
Similarly to the coancestry matrix problem (see #47 (closed)), genetic and allelic parameters are calculated in quite an inefficient way due to how the classes are organized (#48 (closed)).
We now need to generate a version of the program that can deal with large input file without needed days to compute. This is going to be solved reading alleles from a matrix via an index (ie. ignoring the Population
to Locus
set of classes ).
The matrix that are going to be used does not track information about the subpopulations, but just for individuals, loci and alleles. We must be careful that this does not result in calculation errors.
