Haskell library

[Lennart Augustsson]

The Haskell library seems to be contain few entries
(none to be exact), so I've decided to add something.

On animal.cs.chalmers.se I've placed two very simple,
but useful modules.  One implements a random number
generator (a very good one; I didn't design it), and
the other a sorting function that is reasonably efficient.

Share and enjoy!
