A shower counter hit can now be multiple samples, with a different
  number of samples allowed for positive and negative tubes.
  GetData(signal) now returns the sum of all the samples.  This should
  still be compatible with fastbus ADCs as they are a single sample
  (which is already the integral.)

  Modify THcFormula and THcParmList to match changes to THaFormula
     (needed for reports)
  Small changes in THcInterface and detector classes for compatibility
     with new OO decoder and podd 1.6

     Edit debug outputs in THcSHower and THcShowerPlane classes. Group
     outputs preferably by the end of methods, for smooth code
     flow. Structure tests of outputs for easy reading.

    Add fdbg_raw_cal flag in THcShower.h.
    Initiate fdbg_raw_cal with engine's hdbg_raw_cal in THcShower::ReadDataBase.
    Supply calorimeter debug flags to otherwise free print-outs in the
    THcShower and THcShowerPlane methods.

Re-arrange, modify and make more detailed comments in the Shower*.h header
files. Add more comments in the Shower*.cxx files.

Started with Simon's code, but reworked:
	Use podd style arrays in RVarDef.
	Get plane names (1pr, 2ta, 3ta, 4ta) from parameter file.
	Get block counts from parameters instead of hardwiring.
	Rename histogram names to be A,B,C,D 1-13, instead of 1-52

1) Add test for root version when filling sighit1
2) Fixed line which had wrong order in Set and needed two integer values
   sighit1->Set(1,(Int_t)(hit->fADC_pos - 470.7));

for older ROOT version wasn't working.

add simple code to register ADC and TDC hits into global
variables so that hit maps can be made.

Add ThcSignalHit class
