Comment (by novoselt):
Thinking of making `aris` (a variant of spelling arris, "the sharp edge or
salient angle formed by the meeting of two surfaces especially in
moldings") an alias for `ambient_ray_indices` ;-) Would make doctest a bit
shorter.
Still have a bug in fan isomorphism and another one in representing
morphisms as polynomial maps. Problems tend to stem from either
fans/morphisms involving sublattices, which seem to be easy to fix, or
from not dealing properly with torus factors, which are more involved.
