This adds code to convert from a
fuse_msgs::SerializedGraphinto the GraphViz DOT format using the Boost Graph Library (BGL) and a node to dump/write the resulting graph into a.dotfile that can be visualized withxdotorGephi.This PR is on top of #99, which should be merged before this one can be reviewed.
