This reverts commit 4f25d438.

We do this from multiple subdirs

They are only to a lesser extent important for our HPC applications
and the vectorization algorithm struggles with the complexity of the
search space.

It would be hard to implement on top of the latest feature and contradict
features projected for the near future.

By implementing repr such that instance addresses are
not part of sorting anymore

It does not yet do all the jobs it can do, but it exists and we can
run tests with it.

by introducing an order on the kernel objects and
using the first n kernels instead of an itertools.permutations
generator

We will need even more "levels" in the near future

So far, it did not set the qp tuple correctly and
thus sometimes resulted in too big numbers being
chosen.

Instationary stuff not fixed so far.

Now working apart from iteration order deterministicness
