Another idea from today's workshop.
Basic solution idea:
generate 3 random inputs
evaluate student function (s) and model solution (m) at those inputs. Call those output s1, s2, s3, m1, m2, m3
check that (s2 - s1) / (s3 -s2) is close enough to (m2 - m1) / (m3 - m2)
convert to multiplication to avoid division by 0 errors.
