PSE125 holds information about setting of F250 modules. Now this
information is used to set `fNPedestalSamples` and `fNPeakSamples`
parameters of `THcRawAdcHit`.

This is done through `THcHitList`, since it has information about
which crate and module each channel is in. Currently, the information
is set for each event, because of the hitlist and analyzer design.

I added the neccessary support for these changes to all raw hit
classes.

This makes the code nicer and with less duplication in logic.

Along with that I had to correct all the call sites to the RawHodoHit in all the
classes that use it.

The f250 modules can produce at most 511 samples (9 bit) so it seemed reasonable to increase
the maximum number of samples in the raw hits to this value.

  Raw hit reports # of expected signals and their types (ADC vs TDC)
  Raw hit accept and deliver flash ADC sample, and pulse data
     (pulse integral, dynamic pedestal, time and peak)

- Added range checks when adding data to hits. Now an error
is thrown instead of potentially getting core dump.

  THcRawHodoHit gives reference time corrected TDC values
  THcScintillator plane adds a per plane offset to the raw tdc value
  First positive TDC value after adding offset is used

  (Assignment probably not actually done with these objects,
  so we might want to remove these methods.)

   Don't repeat comparisons of tdc values
   with fScinTdcMin and fScinTdcMax because hits only get added to
   fHodoHits (and previously fPosTDCHits, fNegTDCHits, ...) if
   the times are within these ranges.
  In THcHodoscop, remove members of fTOFPInfo that are just used
   locally.

  This is anticipation of a new hit class for processed hits.
  To make it clear that this hit class is for decoding into hit lists

  Friend the detector classes that need access to the private members.
  May later want to use member functions to access the data.

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

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.

Some progress on generic Decode method.
