(Assignment probably not actually done with these objects,
  so we might want to remove these methods.)

  May want to use a hit class that doesn't inherit from THcHodoscope
  as the Cerenkov is not using Neg tubes or TDCs.

  Separate methods for ref time subtracted and raw hits

used to determine focal plane time for each hodoscope plane.
Add code to THcScintillatorPlane:DefineVariables to write out
focal plane time, number of paddles hit that passed minimal TDc cut
and number of paddle hit that were used in determining the focal plane time.
Add calls to THcScintillatorPlane.h to Set and Get the focal plane time
and number of paddle hits used to determine focal plane time for each hodoscope plane.

  Nint of an Int gave a compiler error in newer gcc
  Commented out local variables that are not used

  Rename ScalerLoc so it doesn't conflict with class of same name in podd
  Ignore .pcm files
  Makefile does version check for root 6
  Address warnings in hodtest.C

       This is to match the class name defined in those files
       Also add THcShowerHit to the Makefile

    shms-calo-test directory comprises codes for testing. The 1-st
    layer of SOS calorimeter mimicks the SHMS Preshower, and positive
    side of the 2-nd layer mimicks fly's eye part.

THcShowerHitCluster.cxx.

THcShowerHitClass.h file.

fly's eye part.
