Adding a lot of distributions sounds fine to me. That many distributions
would need to go into a separate namespace.

Any additions should be complete though (the Matlab code only has pdf/cdf)
and well tested. The Matlab code doesn't look all that useful except for
the references ("coding style is not great" is really too kind). I also
don't trust the BSD license that's put on it, many files have different
author names in them with no mention of where they came from.
