first track from the HMS shower counter code.

    Remove variables and code related to the maximum cluster of hits,
    and association of a cluster to the 1-st spectrometer track in
    THcShower.h and THcShower.cxx. Those were used for testing of the
    code, not needed any more.

Access the energy of the golden track from THaGoldenTrack.

    Include THaTrack.h in THaGoldenTrack.h.
    Add GetEnergy method in THaGoldenTrack.h.
    Define variable name "e" for the energy of golden track in THaGoldenTrack.C.

Changed column and row numbering in THcShowerHit.h in order to get rid of
warning messages on unsigned and integer comaprisons when compiling;

Corrected a debug message in THcShower.cxx.

  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.

GN: finished debugging the hodoscope start time calculation. Results match 1-to-1 the corresponding "engine" result.

    Define constants (e.g. plane counts) that are not defined in
    the ENGINE parameter files so that the detector classes
    can be more generic.
    Hodoscope and Aerogel now pick up plane and tube counts from this file

    Register some more variables for the tree
    Clear fNelem of some arrays, not fNhits.
    Print method to print Aerogel pedestals.
    Make Pedestal analysis a bit more like the ENGINE.
    Initialize counters

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.

don't add to histograms.

to the (Hall C ENGINE style) map file being used.

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

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