Lccp
Make header files accessible
Permit derived class access to base class methods and variables
Core ICP routine virtualized

The ICP pose estimation routine is a critical component of the
class. Virtualizing performICP allows for development using
derived classes with a overriding (custom) performICP routine of
its own, without tampering with PCL's own version
Make these functions accessible to derived classes
Support mesh extraction from multiple pcd files
Camera pose files record more precise model
A slightly coarser TSDF volume (8mm) frees up GPU resources for other tasks.
Additional class variables that need to be set when this function is called
Use correct VTK_INCLUDE variable (vtk-5.8)
Necessary cmake include path variable for vtk (vtk-5.8)
Missing install dependency
Expose parameters that control bilateral filter applied to raw depth data
