> There is a class called {{StepPosition}} that is smart about creating unique ids for steps. Unique, deterministic creation of step ids is important. However, what we have now is expensive. When I original did this, I created an string ID scheme where you could find your location in the traversal, by the id "[0:[1:[2:3]]]" (first step of the root traversal is a traversal parent -- the third step of the second traversal). Why I did it like this I don't know why??! ... Instead, I think we can make things both faster and simpler:
> 1. Change {{Step.id()}} to an integer, not a String.
> 2. Step id labeling is simply walking the traversal tree in a deterministic depth first manner and incrementing a {{nextId++}} counter.
> We can do 2 without 1 and it would not be a breaking change.
