This patch implements the principal and exponential specialisations for
symmetric functions as given in Stanley, Enumerative Combinatorics,
Section 7.8.
Unfortunately, the patch currently has several problems:
1) it seems that always the default code in sf/sfa.py is called, I don't
know why
2) I do not know how to give the desired default argument 1 the correct
type in exponential_specialization
3) I guess one should rather implement this for quasi-symmetric functions,
but I do not know enough about these currently
4) the documentation and sensible tests are still missing
