moving packages in from collision_environment and regenerating stack.xml in preparation for consolidation
Massive change for moving to arm_navigation_msgs
added signed distance field, may not work at this point
signed distance field implemented
Building against unstable, taking out gazebo_msgs dependency for now, and incrementing minor version for release
added unit tests
starting conversion process of propogation distance field to support the removal of obstacles
moved array/voxel structures to new int3 struct
removed visualization/marker publisher from inside the distance_field
convert to use eigen vector instead of struct
added ability to remove voxels from the distance map
tracking obstacle voxels.  Added iterative updates
removed testing function
updated collision_proximity to use the new distance_field getMarker functions
fixing bug in distance_field, adding another accessor for getting markers
make code compile under Groovy
picked distance_field package from arm_navigation_experimental repo
Merge branch 'master' of arm_navigation_experimental
