added a check in organized_connected_component_segmentation
PCLVisualizer: Create CoordinateActorMap in all constructors.

The missing initialization causes a segmentation fault in
PCLVisualizer::addCoordinateSystem, e.g. when calling pcl_viewer with the
"-ax" parameter.
pcd_viewer: Do not set debug flag to false when parsing arguments.

This produces a better error message and avoids a segfault when too few
elements are given on the command line.

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
