  Hall D Geometry Data Base: Downsteam scintillators for Charged Pion Polarizability
  **************************************************

     version 1.0: Initial version	-ST

By default these detectors are not enabled in the standard Hall-D geometry in
HDDS. Here is how to enable them:

in main_HDDS.xml
=================
1. uncomment the line for the CppScint in the "forwardPackage" composition
