Erase ^M from --snps file.
Allow one or more spaces between arg and value
Use hypergeometric instead of binomial

This applies only to binary matrices and not continuous matrices.

To calculate a score for each locus-column pair, I previously used the
binomial distribution, which assumes sampling with replacement. Now, the score
is calculated with the hypergeometric distribution, which assumes sampling
without replacement.
Report genes in the matrix that lack intervals
