Zalathar d36e2b88d6 Incorporate iter_nodes into graph::DirectedGraph
This assumes that the set of valid node IDs is exactly `0..num_nodes`.

In practice, we have a lot of graph-algorithm code that already assumes that
nodes are densely numbered, by using `num_nodes` to allocate per-node indexed
data structures.
