Work in progress / proof of concept, but the following file patches
examples/csma-bridge.py to make it scan the (wired) topology by ns-3
introspection, creates a graphviz graph (requires python graphviz bindings),
does a "twopi" layout, prints the resulting node coordinates, and finally
generates a postscript file (as demonstration).

This just to demonstrate it is possible ;-)
