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.

for a detector.

the Hall C style detector map.

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.

Going to back out of this and go to multiple inheritance.

Copy the intermediate classes needed for THcHodoscope.  Many
changes needed.

Some progress on generic Decode method.
