Podd no longer has the hana_scaler directory.

Also, on the advice of Stephen Wood, remove references to INSTALL_DIR (evio)
and now only check for EVIO_LIBDIR and EVIO_BINDIR.  Also, suppress
compilation of the evio libraries (as those directories may not be world
writeable.  So, the assumption now is that local installations of the
evio libraries will be done correctly (by the local user or the local
system administrator).

  Makefile and THcInterface changes to reflect the changes in podd

JLab, if it does not exist locally already.

  These are left over from early development when there wasn't a table
  drive way to retrieve parameters.
  (Now we use gHcParms->LoadParmValues())

from the raw hit adc value when calculating the ADC corrected time.

  in calculation of drift chamber start time

  Pulse height corrected times saved in THcHodoHit objects.
  PulseHeightCorrection method renamed to EstimateFocalPlaneTimes
    because the pulse height correction is now done in the
    ProcessHitsMethod.

   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.

  Eliminate usage of GetParent() many times every event.

Fix problem in THcScintillatorPlane.cxx and add debug statement used in THcHodoscope.cxx

When totolerance is large then jmax can legimately equal zero
since in effect there is one bin in the histogram.
No reason for the if statement

  Modify THcFormula and THcParmList to match changes to THaFormula
     (needed for reports)
  Small changes in THcInterface and detector classes for compatibility
     with new OO decoder and podd 1.6

  Enforce variable conventions
  Default using_scin and using_prune selection to off
  Break different track selection methods into different class methods

section of THcHallCSpectrometer to be clearer.
Does not follow the fortran in detail, but should be doing the same
thing.

  There is some unclear code in the track selection that could
  do with improvement.

  Move hodo_slop retrieval to THcHodoscope
  Get fPosCenter array length from fNelem instead of fixing length at 16
  Remove now unneeded THcScintillatorPlane creation method

  Don't start variables that are not member variables with f
  Declare temporary variables as locally as possible
  Remove some unused member variables from THcHodoscope.h
