Comment (by tscrim):
I stated explicitly that we're following [GR1989] in the class doc and
changed the QQ-algebra requirement. For the refinement order, I don't
think there is any ambiguity, but from the rest of the docstring, it must
be that `q <= p` is `q` refines `p`. I removed the D-basis paragraph
because `D([1, 3])` should be standard syntax (at least following the
symmetric functions and I forgot to test it for the D basis). I fixed this
so that it works now.
