Changed the raytrace range to be longer
Changed the unknown threshold from the default value since it seems unreasonable, dont think it makes any difference since it would work very poorly if this was taken into consideration
Added the new footprint as a comment
Changed stuff to work with new hydro pcl, removed unnecessary stuff
Merge branch 'hydro-devel' of https://github.com/nilsbore/scitos_2d_navigation into hydro-devel
Tidied up the code a bit
Set the unknown threshold back to 6, may change again later
Merge pull request #32 from nilsbore/hydro-devel

Made changes to make the chest camera processing nodes work with hydro, pcl 1.7
