Comment(by novoselt):
OK, my patch looks big, but the only real change to the original is taking
the absolute value of the dual scaling factor, so that normals remain
inner.
In addition I (hopefully) made doctests more clear, since they do appear
in the documentation. Polytopes are now created using coordinates of
points with all the necessary transpositions after that. I also made
doctest lines shorter for better looks of the documentation.
I have changed "parallel" to "orthogonal to integer kernel" in the
description of normals (and now I do remember that I didn't like this
"parallel" when I wrote it...).
If you are fine with all these changes, I will switch it to positive
review. Thank you for catching this bug!
