 This won't be that hard.

 (Famous last words.)

 We "just" need to make the part of the code that constructs the
 probability distribution for the known nodes separable from the part that
 chooses a node based on that probability distribution. Then, we need to
 write unit tests with an example nodelist to make sure that the correct
 properties are obeyed. As a part of that, we might want to make sure that
 every rule in the code is tested, and every rule in the code is in path-
 spec.
