After digging deeper into cython, I made some more improvements. Here
are the new benchmarks:

Hi Nicolas,
thanks for your review... I folded your comments and made some first
changes containing in particular some minor speedups in mulitiplying
elements.
I looked into the code for the CyclotomicField(n), and the
multiplication and addition seems to be at least not faster than in
UCF, but -

Hi,
after Sebastian's explanations how to push things to the combinat
queue (thanks again), I pushed a first version of the universal
cyclotomic field. If anyone has some time, it would be nice to get
some feedback what runs smoothly and where is still work to be done...
You get the universal cyc
Hi Christian!
It's great that you are working on this! That could turn up useful
for the workshop next week.

As described in ticket #8327, I have some questions about implementing
the universal cyclotomic field:
At the moment I only have a cyclotomic field for a given integer n,
called - so far - NewCyclotomicField. It is a CombinatorialAlgebra
generated by the appropriate Zumbroich basis together with
m
