The "transform_tolerance" parameter actually applies only to Costmap2DROS
objects (
http://www.ros.org/wiki/costmap_2d#Coordinate_frame_and_tf_parameters) and
not to NavfnROS. Much older versions of NavfnROS required the
transform_tolerance parameter, which is probably how you ended up finding a
navfn_params.yaml file, but the tutorial would be more correct if the
navfn_params.yaml file was left out altogether or if it was used to set the
"allow_unknown" parameter which is the only parameter read by NavfnROS -
http://www.ros.org/wiki/navfn#Parameters. For now, I've changed the tutorial
to set the "allow_unknown" parameter to its default value as it might be
useful for people to see how they could set parameters on the NavfnROS

Hope all is well,
