Comment:

 Doing this, I have encountered and solved some problems:

 * The generators of permutation groups were returned as a list and not as
 a family, which is the case for other types of groups. They are now
 returned as a family.

 * The Hopf algebra structure didn't include counit. This has been
 corrected.

 * There was a bug in module_morphism which didn't work when the codomain
 was the ring itself (because it is not considered as a module by sage). It
 has been corrected.
