Main change was to allow the beam X and Y positions and angle
at the target to be read in through parameters instead of
always using the EPICS data. This gives added flexibility.

If either of the beam position parameters (gbeam_xoff or
gbeam_yoff) are read-in as parameters, then the code uses
the read-in parameters as the BPM position at target. If
there are other beam position or angle parameter that are
not read in then they are set to zero.


1) Modify THcRaster.h
   a) Added variables for X and Y beam angles at target.
   b) Added variable fFlag_use_EPICS_bpm which is a flag
     that is determines whether the code uses the parameters
     or EPICS reads.

2) Modified THcRaster.cxx
   a) set default BPM z-positions to Fall 2018 survey.
   b) Modified Process method so that the BPM position/angle variables
     that are set by parameters are no longer recalculated. Just
     use the existing variables fXbpm_tar, fYbpm_tar, fXpbpm_tar
      and fYPbpm_tar throughout the method.

Add the variable ebeam_epics to the tree. This is the EPICS
value of HALLC:p  . For now this is good for monitoring changes in the
beam energy but needs to be check how it compares to the Hall C
beam energy measurement.

1) Add tree variables for the three BPMs and projections to target
in the EPICs coordinate system (+X beam right, +Y up)
rb.raster.fr_xbpm_tar
rb.raster.fr_ybpm_tar
rb.raster.fr_xbpmA
rb.raster.fr_ybpmA
rb.raster.fr_xbpmB
rb.raster.fr_ybpmB
rb.raster.fr_xbpmC
rb.raster.fr_ybpmC

2) Modified code so that it only modifies the BPM variables if they
are all !=0 ( beam on) . Otherwise it sets them to the previous EPICS
read. This gets rid of all zero EPICS reads,except if the first EPICs
read the beam is off.

3) Removed the reading of gpbeam from the global parameter list in the Process
  method and just have it in ReadDatabase.

4) Change the calculation of beam at target to use the projection of
   BPM_A and BPM_C instead of BPM_A and BPM_B.

5) Remove setting the raster position to the hcana beam coordinate system
   with (+X beam left). The raster is in the EPICS coordinate system.
    This makes it easier to interpret the carbon hole runs.

Add default values for optional values of
+   fgbpma_zpos = 370.82;
    fgbpmb_zpos = 224.96 ;// cm
    fgbpmc_zpos = 129.30 ;// cm

instead of zero.

Otherwise the code would get NaN for the calculated target beam position
since it was divied by zero unless this the parameters are set.

Handle cases where BPM information is unavailable/zero.

Change raster x/y position calculation to cm (from mm).

Update calculation of fPosition and fDirection in THcRaster.cxx

Fix minor bug in calculation of fDirection

  Add doxygen groups "Apparatuses" and "Decoders"
  Make sure every class is in a group
  Make sure most classes have a \brief description
  Improve comments for some classes including THcHallCSpectrometer
     and hodoscope classes
  Change some Doxyfile defaults.  Include sources files.

When filling beam position that is used in determining the reaction
  point multiply the raster X by -1 to put in the right handed coordinate system

The raster coordinate system is left-handed to match the EPICS beam
  coordinate system.

Switched X and Y rasters to make them consistent with epics left-handed coordinate system, and changed sign of x in fDirection() to make the beam position a right-handed system

Edited CalculatePedestals() method to correctly fill rasters, and corrected typos in fYA_ADC and fXB_ADC when calculating the currents

The calls to `Find()` need to be wrapped in checks if returned pointer is null.
Otherwise a further call to get value produces SegFault. The `LoadParmValues()`
does not suffer from this, since it throws error if non-optional parameter is
not found. The error message also tells which parameter is missing.

I still left three calls to `Find()` in `THcAnalyzer.cxx`. They are wrapped in
checks and some other things...

  Otherwise InitHistlist doesn't have the detector map
  and can't do setup of reference time stuff or sanity checks on the
  detector mapping

Added the raw raster ADC values to the histos and trees. Modified the ranges and binning of the
histogram definitions in output_bpw_.def accordingly.

In raster_jun04.map, reassigned the raster channels into a single plane instead of different planes.
This makes it easier for comparision with the engine.
Modified raster_test.C to analyze run 52947 in the cache directory.
Some minor clean up in the THcRaster.cxx class- removing comments and unused variables.

Read gpbeam in THcRaster::ReadDatabase
Add jan05.kinematics
Modified DBASE/raster_test.database to fill g_ctp_kinematics_filename
with DBASE/jan05.kinematics
Modified raster_test.C to load g_ctp_kinematics_filename

  Fixes not necessarily correct, just avoid the errors.

  Files with the prefix raster_ are coppies of original *.database,
  and *.param files which now includes changes nessacery for
  decoding raster data. I created seperate files for these because I
  need to merge this code upstream before I can compare the raster
  decoding results with that of the analyzer. For e.g. the map files are
  different from the original map files. So Steve needs to create a perl
  script that can propgate these changes in the map files to the map
  file of the analyzer inorder for me to do the analyzer hcana
  comparision. Once the comparision is done and we are satisifies with
  the results, we will merge the changes with the original files and
  remove the files with the prefix raster_*.

  gbeam.param now included by general.param.  No need to load
  a separate parameter set to test raster/BPM code.

  examples/MAPS/raster_jun04.map adds new detector IDs for the raster
  and BPMs as follows:

Add the following IDs to the misc elements,
BEAM
 RASTER_ID= 18          ADC
 BPM_ID= 19             ADC

In the channel section did the following modification:
 sub , plane, counter, sig
  14, 1, 13, 1 !ADC ROC#1 Sl#15 Ch#14 Fast Raster X-sync
  15, 1, 14, 2 !ADC ROC#1 Sl#15 Ch#15 Fast Raster X-signal
  12, 1, 15, 3 !ADC ROC#1 Sl#15 Ch#12 Fast Raster Y-sync
  13, 1, 16, 4 !ADC ROC#1 Sl#15 Ch#13 Fast Raster Y-signal

  THcRasterRawHit class to helps with the decoding of the raster
     signals via THcHitList class.
  THcRasteredBeam class derives from THaApparatus to handle rastered beam.
  Modify Makefile and HallC_LinkDef.h to compile new classes

Added coding for read parameters from the hcana.param file.

In the hcana.param file added the four raster channels
graster_channels = "xsync xsig ysync ysig"

Created raster_test.C script to run the analyzer for raster code testing purpose. This was coppied from the hodotest.C
