patches on github, metis export routine, work on osm
I have added in better error checking and removed all the unused variables (but the asserts were not turned on and some got broken).
need to rework the code so that it uses ifdefs around the variables that are only needed in assertions, or change the asssertions to do the evals inline.

You are free to take those back into your code.
I am working on using metis on the openstreetmap graph,
