Solving compiling error for pcl_gpu_octree
Merge pull request #177 from mmunaro/master

Moved common/pcl/common/impl/sse.hpp to common/include/pcl/sse.h.
Rework of Supervoxel classes
  Changes in octree:
    Renamed OctreePointCloudSupervoxel class to OctreePointCloudAdjacency
      This is now a general class that can be used for any point type
    Added OctreePointCloudAdjacencyContainer
      This class allows for storage of a data member in leaves, for things like segmentation
  Changes in segmentation:
    Renamed Supervoxels  to SupervoxelClustering.
      Now uses OctreePointCloudAdjacency instead of OctreePointCloudSupervoxel
      Allows for providing a transform for octree calculation
      Returns a map of supervoxel objects, rather than a pointcloud of PointSuperVoxels
  Changes in apps:
    Renamed voxel_superpixels tool to supervoxels to match with class update
  Changes in examples:
    Changed segmentation/supervoxels to use renamed class, enhanced functionality and display to better show supervoxels
Added unit test for OctreePointcloudAdjacency
Added eigen aligned allocator to vector declarations in supervoxel_clustering
Cleaned up code in octree_pointcloud_adjacency (removed commented-out code)
Added option to disable transform in example_supervoxels
Fixed small bug that occured due to voxel_data values not being initialized.
Added tutorial for supervoxel clustering
Changed examples/segmentation/example_supervoxels.cpp so that graph creation is consistent with how it is done in tutorial
Switched all instances of XYZRGB to XYZRGBA
Updated cloud_composer tool with XYZRGBA change
Update to Supervoxel Clustering Tutorial
Added more figures, extended theoretical primer to help with understanding of what is going on.
