Added:
   trunk/scenes/particleCGTTest.cc
   trunk/scenes/pcgt.cc
Removed:
   trunk/scenes/private/
Modified:
   trunk/scenes/CMakeLists.txt
Log:
Removed private directory from scenes; if necessary files exist and nrrd 
particle datasets are enabled, build scene_pcgt and show option for 
scene_particleCGTTest
