* example, the existing implementations of this method explicitly add the supplied nodes to the
* graph, and then call {@code graph.addEdge()} to connect the edge to the nodes; this is not part
* of the contract of {@code graph.addEdge()} and is done for convenience. In cases where you want
* to avoid such side effects (e.g., if you're testing what happens in your implementation if you
* add an edge whose end-points don't already exist in the graph), you should <b>not</b> use this
