Comment (by jason):
I don't see what to doctest. I personally didn't come across any errors,
I'm just adding the checking as good programming practice. As for the
shortcut in the nonplanar case, I'm just doing exactly what Boyer does in
his C program. The program gave the correct answers before, now it just
doesn't worry about finding a kuratowski subgraph if it is not needed.
Again, I didn't see any errors before, so I can't put in a doctest that
didn't work before, but does after the patch. This is pro-active
bugfixing, not reactive bugfixing :).
