prepended to all variables in the DBRequest list.

detector parameters from the gHcParms (THcParmList).

Use cut file to determine what is a pedestal event.  Pedestal events
only proceed to Decode.
In Decode (Just THcHodoscope for now) loop through each plane and accumulate
pedestal data.  Calculate the pedestals at the first non-pedestal event.
Pedestals are just calculated, but nothing is done with them.

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));

use the run number to determine which parameter and map files to use.

string variables from the Hall C style parameter files.  String
variables are loaded into a THaTextvars object that is held in the
THcParmList object.  PrintFull will now print all the string variables
as well as the numerical variables.  Added GetString, AddString and
RemoveString methods to access and modify the string variables.

for older ROOT version wasn't working.

number of planes and Plane names are still hard wired.

function or detector.

be made either in output.def or by analyzing root tree.

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

Add ThcSignalHit class

Follow SRC model and make a scintillator plane class.

TClonesArray ConstructedAt method.

Raw hit class for drift chambers and skeleton drift chamber that prints
out drift chamber package hits.

Move Compare method from THcHodoscopeHit to ThcRawHit since it should
work for any derived class.

Get detector name -> ID mapping from the map file comments

TClonesArray ConstructedAt method.

work for any derived class.

THcHodoscope, a multiplane scintillator array.  Make a Hall
C style spectrometer (so that default Hall A detectors are not
included.)  Can read a Hall C data file and print out hodoscope hits
where the left/right TDC/ADC are matched up per counter.

constructors so that they now work in TClonesArray.
