Maybe the class {{{IncidenceStructure}}} belongs in its own module, say
{{{incidence_structures.py}}}? Which directory it goes in might does not
matter so much, so why not put both in designs? What do you think?

I just saw your post regarding a {{{subspaces}}} method for a
{{{FreeModule}}} over a finite field. I'll work on that next.
(I don't think I need the projective case - as you pointed out in your
second post it is a trivial consquence of the affine case.)

Will do. Please let me know what you think of the above
{{{IncidenceStructure}}} idea though.
