Ralf, I suggest that you (or me, if you like) merge the docs I have written for
Compose in iso-experiment, with trunk. THe outline of the algorithm for
isotypes in trunk is outdated.

isomorphismTypes: Partition L -> Generator % 

in trunk.  If you like, we can duplicate (with svn cp) iso-experiment, and do
that there -- I think that would be very easy, in fact.

Much more sensible I think would be to express the same functionality with
MultiSort species. Do not forget: we won't be able to generate Isotypes of
FunctorialComposition, thus, to take them as an argument for the representing
isotypes by representatives :-) is unfortunate.

I think that Permutation, Cycles, etc. should be moved to an "examples" files,
as I have started it in iso-experiment. species.as.nw should only contain the
"natural transformations" and everything they depend on, don't you think?

Martin
