This is actually che... -
- Is this valid now? something along this lines is valid.

It is sad to do so, but I have no idea h... -

- MinGens now truncates to the max degree of the generators.
Can be considerably faster than before, of course.

- Implemented.
Meanwhile I made a few tiny changes in the direction of the Framework/Mill.
Tested, seems fine.
Now...
