    17  // Defines one of the base iterators, the All iterator. Which, logically
    18  // enough, represents all nodes or all links in the graph.

    20  // This particular file is actually vestigial. It's up to the QuadStore to give
    21  // us an All iterator that represents all things in the graph. So this is
    22  // really the All iterator for the memstore.QuadStore. That said, it *is* one of
    23  // the base iterators, and it helps just to see it here.
