we really have to refactor these run binaries to use actor or worker. every time we refactor or add stuff we always break these things...

[dnesbitt61]

I thought about that for a minute or so, but don't have much time today. one thing this does though is compare CostMatrix to TimeDistanceMatrix which can be useful.

yep, to do it right we need to build into the workers/actor a way to control a bit what it does underneath. totally understand not having enough time for it!
