What would you suggest? Would you care to write a few? I think
KroghInterpolator is fairly thoroughly tested at this point, though I
guess a few checks that it raises sensible errors when fed erroneous
input wouldn't hurt.
More generally, is it worth putting something in the tests for
numerical code about stability? An example with degree thirty, say,
and a reasonable error estimate, to make sure that modifications don't
make the code less stable numerically?
