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.

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.

so that each detector can have access to it to build it's own detector Map
from the Hall C style detector map.

rather than relying on a modified THaDetectorBase.  Just commit is
just the renaming and deleting of files we don't need, no code changes.

Some progress on generic Decode method.

Work on Decode to hitlist method in DetectorBase
