SFS Estimation
This method will estimate the site frequency spectrum, the method is described in Nielsen2012.
This is a 2 step procedure first generate a ".sfs" file, followed by an optimization of the .sfs file which will estimate the Site frequency spectrum. For the optimization we have implemented 2 different approaches both found in the misc subdir of the root subdir.This is shown in the diagram below.

- -realSFS 1
- an sfs file will be generated.
- -realSFS 2
- snpcalling (not implemented, in this angsd)
- -realSFS 4
- genotypecalling (not implemented, int this angsd)
