New class THcDC is whole set of wire chambers.
  THcDriftChamber is one chamber (6 planes)
  Implement space point finding from h_pattern_recognition up to point
     before where space point lists from the two chambers are combined.
  Includes
      FindEasySpacePoint   (h_find_easy_space_point)
      FindHardSpacePoints  (find_space_points)
      DestroyPoorSpacePoints (h_sp_destroy)
      SpacePointMultiwire  (h_sp_multiwire)
      ChooseSingleHit 	   (h_choose_single_hit)
      SelectSpacePoint	   (select_space_points)

Space points are arrays of structures in the THcDriftChamber class.  Will
probably need to take space points out class so that they can be looked at
at the THcDC level.

New code is only tested to see that it compiles and that space points
are sometimes found.

      Start adding to the drift chamber code.   Setup a class structure
      similar to what podd uses for the VDCs.  Raw hit class renamed
      to THcRawDCHit.  Signal hits are how THcDCHit, modeled after
      podd hits.  Add THcDCWire, and classes for time to distance conversion.
      Time to distnace conversion doesn't do anything yet.

      Find some improved DC parameter files so that min and max TDC limits
      are good for the run we are using.

      THcDriftChamberPlane asks ThcDriftChamber for many parameters.

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

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.

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.

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

from THcDetectorBase

Some progress on generic Decode method.

Make setup scripts work from anywhere (so can be added to login script)
Makefile builds the Hall A analyzer.

that includes a class to read CTP style parameter files.
