Fix for problem where leaves could get lost, and warning would show up. Now we use leaf indices directly for seeding, instead of doing a look up
Changed OctreePointcloud Adjacency to use std::list instead of std::set, added comparator to SupervoxelHelper so that the internal set of voxels owned by a helper is sorted by index instead of memory location
Added brief comment explaining comparator
Removed public interface for modifying neighbors of OctreePointcloudAdjacencyContainer. Neighbors can now only be added/removed from within OctreePointcloudAdjacency. This does *not* mean neighbors can't be modified, just that the list of neighbors itself can't be modified.
Updated supervoxel examples with normals and better description of the camera transform
Change to visualization to make things a bit nicer - mainly removed broken opacity
