New description:
When we want to design a Hopf algebra, we ask "Where can I find a good
code?" and the first idea is "The symmetric functions..." Wrong...
In this ticket I try to provide a simple and efficient design such that
this becomes fast to implement a graded connected hopf algebra (see:
`sage.combinat.hopf_algebras.example.fqsym.py`).

Comment (by elixyre):
I'm to tired to add some comment and documentation in
`sage.combinat.hopf_algebras.__init__.py`...
Mike, could you read the code of this file such that we discuss about the
design? Other comments are welcome...
