Comment (by ncohen):
Could you add some comments ? So many loops and tests, even an internal
caching system and no comments is a bit tough.
Also, I don't think you should implement caching systems like that in a
`find_` function. If we need such caching (and we do) it should be
implemented where it belongs, with a dedicated function.
I had in mind something like that:
{{{
designs.orthogonal_arrays.build(k,n)
designs.orthogonal_arrays.build_information(k,n)
designs.orthogonal_arrays.is_available(k,n)
designs.orthogonal_arrays.exists(k,n)
designs.orthogonal_arrays.max_k(n)
designs.orthogonal_arrays.all_n(k, min=None, max=None)
}}}
Though I like this interface, it means quite some amount of copy/paste in
the code. For TD and MOLS. Maybe there is a trick.
