Added the option to have an extra head camera, with a higher voxelgrid
Forgot to change the height
Tidied up a bit and changed to the correct topic
Fixed the parameter settings, it actually works
Removed unnecessary code and switched to the topics used in backtrack
Removed commented code
Changed the unknown_threshold to 9 as well for consistency
Merge pull request #13 from nilsbore/backtrack
