Code should be run inside it blocks, not describe blocks: it blocks are run asynchronously to generate test blocks so currently all logs done by user function will be bunched together before any test blocks, and makes debugging impossible.

What if there are multiple shortest paths? The kata doesn't specify what should be done in this case.

(This needs to be handled when random tests are up.)

Random tests missing. Guess they will be forever missing since author is looong gone
