  Hall D Geometry Data Base: Forward MWPC for Charged Pion Polarizability
  **************************************************

     version 1.0: Initial version	-DL

     version 2.0: Modifications according to drawings from March 2021  -BZ
                  Really basic, needs improvment on the first absorber layer lead	          

By default this detector is not enabled in the standard Hall-D geometry in
HDDS. Here is how to enable it and the rest of the geometry changes needed
for the CPP experiment:

in main_HDDS.xml
=================
1. uncomment the line for the ForwardMWPC in the "forwardPackage" compisition

2. comment out the line for the ComptonEMcal in the "forwardPackage" compisition
   (since it occupies the same space)

3.
