In
http://trac.sagemath.org/ticket/17626
the group class should have a newly created monoid class as a base. At
the moment the group and the monoid parent do not have much in common
(but their elements have).
I've started implementing this, but have a rather strange problem. See
below the output of "sage -t" of the commit c51a914.
Any ideas what goes wrong?
