Johnson All Pairs - wrong edge mapping

[Harold Ishebabi <harold.ishebabi@…>]

I checked the example here : http://www.boost.org/doc/libs/1_40_0/libs/graph/example/johnson-eg.cpp

The results are correct. Then, I shortened the graph to 3 vertices and 6 edges (see attached file). The print out of the graph is incorrect (see output : some edges are reversed).

If you run the example, you'll note edge 0->2 shortest path is reported as 90 instead of 98. As well, the dot graph produced is showing wrong edge properties.
