'''OUTDATED:'''
The current "official" version of `p_group_cohomology` is 2.1.4. However,
due to recent backward incompatible changes in Sage, the package would not
install, respectively it would install if some header were present but
wouldn't work.
Hence, an upgrade is needed. While I was at it, I have also improved the
computation of Poincaré series, depth and filter degree type (the latter
now uses a Hilbert-driven computation of Gröbner bases in elimination
order, which works since in that setting the Hilbert function is easily
available), and I added new functionality related with nilpotency.
The new spkg is at http://users.minet.uni-
jena.de/cohomology/p_group_cohomology-2.1.5.spkg
