This will probably cause three way merge hell with #718, but lets be fearless
Removed Supervoxel template parameter from lccp. Now we should get some conflicts with #718
Changes to seeding
Updated seed pruning to use a heap instead of sorted array
If using input normals, don't refine themgit add -i
Added label to supervoxel internally
Initial commit of stratified tracking coherence
Initial commit, stratified sampling. Also changed coherences to have const correctness in compute
Added stratified particle filter, Added ability to create supervoxels from weight map
