Comment (by Rudi):
Hi Nathann,
I think you remember ticket #18183, on matroid polytopes. I saw that
discussion the other day and I had to agree that it is an omission that we
have no `.independent_sets()` method.
I want to optimize the running time. Maybe using
`subsets_with_hereditary_property` is a good choice for the top class
Matroids, I'll check it out. To improve upon
`BasisExchangeMatroid.independent_r_sets()` I will have to work harder.
Not sure even how much I can still squeeze out, we thoroughly optimized
that one. But even if I cannot improve the running time, it will be good
to have `.independent_sets()` in the interface.
