Changed paths:

   M /trunk/src/libraries/TRACKING/DKalmanFilter.h

(1) Fixed bug in third step of 4-step Runge-Kutta for the central
parameter set. (2) Added second order terms when stepping the position
along the trajectory through the field.  (3) copied the old version of
Step for the central parameter to FixedStep and (4) added a new
routine Step for playing around with adaptive step size
algorithms. (5) Get the material properties through DRootGeom and
commented out old DMaterialMap interface. (6) Modifed BrentsAlgorithm
to step from one position to the next instead of always stepping from
the end position used to initially bracket the minimum.  This reduces
the number of steps needed by at least one.

PIDPhoton: photon tags are now enumerated and this functionality is
        propagated into TwoGammaFit object. One obsolete factory that used
        BCAL showers to make photons removed.

TwoGammaFit: unconstrained invariant mass of two photons introduced.
        ChildMom returns photon momenta before the fit while
        ChildFit contains photons after the fit. Deleted DPi0.

Changed paths:
   M /trunk/src/libraries/TRACKING/DTrackFitterALT1.cc

Added a disabled target constraint. This is because there is evidence
that constraining to the beamline (large z-extent) can have a
significant effect on the momentum of forward going tracks. To enable
the contstraint, one needs to set the #if 0 to a #if 1 at the top of
GetWiresShiftsErrs() and recompile.

lines Changed paths:

Add call to RefreshProcessorListFromJApplication from main(). This is
because a call to it was removed in JANA 0.5.0 since it was seen as
redundant. Apparently, the place that it was removed from was needed
to get the MyProcessor registered with the JEventLoop in
hdview2. Hence, the additional call now in hdview2 itself.

with MC (5) remove logarithmic factors from multiple scattering

   A /trunk/src/programs/Simulation/HDGeant/gtrack.F

gtrack.F [rtj]
   - suppress an optimization mechanism in the core geant gtracking function gtrack()
     that makes mother volumes appear empty under rare conditions.  These conditions
     apparently happen frequently when all interactions are turned off, in the presense
     of a strong magnetic field.
Makefile.orig [rtj]
   - add gtrack.F to the list of geant321 library routines that are overridden with local
     copies in the build directory.  Someone will have to make sure that this also works
     with the default BMS build procedure.

Makefile.orig [rtj]
   - I guess that the local copy of gthion.F should also be included as an override
     of the default routine in the core geant321 library (woops!).  This fix was an
     old one and not so crucial as the fix in gtrack().

   M /trunk/src/libraries/TRACKING/DKalmanFilter.h

(1) Added error propagation for lorentz correction (2) Removed wire
origin and direction arguments from FixedStep and CalcDeriv... for
central tracks (3) Added magnetic field vector B as an argument for
CalcDeriv.. for central tracks. (4) Resurrected perturbative approach
for central tracks and redefined D to be the signed distance from the
actual trajectory to to the reference trajectory.  Propagation of D
and the Jacobian matrix elements for D are done assuming a helical
segment.

- Added PLOG and TLOG FFKEY cards to allow sampling from log distributions
  in momentum and theta when using the particle gun. This makes it a
  little easier to focus generated events in the foward, lower energy
  region where we will have more tracks.

- Added comments in physics processes section of control.in to describe
  DRAY and DCAY cards for controlling delta ray and in flight decay
  processes.

- Added DTrackHitSelectorTHROWN so that truth information can be used for hit selection

- Make DParticle factory re-do hit selection rather than simply fit to the hits
  used by the wire-based fit.

- Fix GetAllHits call made from DTrack_factory whihc was passing in kWireBased
  instead of kHelical. Similarly, time-based tracking uses kWireBased.
  (kTimeBased is reserved for finding hits close to the time-based track).

- Reduced the cell size used to calculate the average dist for the FDC to 0.5cm

- Added TARGET_CONSTRAINT configuration variable to allow easy switching of the
  constraint on and off. The default is off.

Modified the track-level tree to include number of correct and incorrect LR choices.
Modified hit-level tree to include LRcorrect rather than simply calculating the
LR for the thrown and fit tracks independantly. The previous method would 
occasionaly lead to a situation where the two where essentially the same, but
there was a sign difference that incorrectly flagged the hit as having an
incorrect LR.

   M /trunk/src/libraries/TRACKING/DTrack_factory_THROWN.cc

- Fixed bugs with DParticle_factory related to using the
DTrackHitSelector class that were apparently not caught before the
last commit.

- Changed the fit type passed to DTrackHitSelector::GetXDCHits() so
that it is helical for DTrack and wire-based for DParticle. This makes
it more consistent with the real reconstruction factories who use the
associated objects to record the hits used in the fit and therefore
the hits selected from the track used as *inputs* to the fit.

the DMagneticFieldMap class was giving the same values as the map
reader/interpolation code in hdgeant were. The latter has since been 
replaced by the former so they are now necessarily consistent.

- Added new DMagneticFieldMapSpoiled class for easily tweaking
  an existing field map in order to study its effects.

Fixed bug in the determination of the origin of a close-packed stereo
wire.  The old version of the code converted the deltax and deltay
values into a radius and then rotated by phi, but a close inspection
of the hddsGeant.F file and the c++ code generating this file shows
that one needs to rotate the (deltax,deltay,0) vector by phi around z
instead.  This led to some small discrepancies between the wire
origins in the simulation file and the reconstruction.  Also put in a
preliminary fix for the wire direction vectors for the close-packed
stereo wires.  These vectors are still not quite correct relative to
the simulation -- perhaps there are some roundoff problems?

- Modified how hits are passed around in the ALT1 fitter
  to (hopefully) make it easier to assign a left/right
  sign independent from the side of the wire the track
  happens to be on.

- Access the Lorentz deflection class directly to apply the
  correction based on the current track. This is necessary
  since flipping the left-right choice requires flipping
  the sign of the Lorentz correction. Since that sign is
  decided based on the segment fit and not the global fit,
  the only way to guarantee consistency is to apply it
  here based on the local (i.e. inside ALT1 fitter)
  choice of left-right.i We also have better angle
  information at every plane which, in principle, should
  be an advantage.

- Added PickupUnmatched method to look for seeds with hits only
  from SL1 and try and pull in stray single hits from SL3.
  CDC events with only SL1 hits tend to have such poorly defined
  helical fits, the wire-based fit fails completely.

- Changed the default value of MIN_SEED_HITS from 3 to 2. Similar
  to above, this allows hits from more than 1 axial superlayer
  to contribute to the helical fit recovering some tracks that
  are otherwise lost.

- Replaced "debug_level" which gets set through the environment
  with DEBUG_LEVEL which gets set through TRKFIND:DEBUG_LEVEL
  config. parameter in a way that is more consistent with the
  track fitter.

- Removed MIN_SUBSEED_HITS config. param. which is no longer
  used.

  info since it is used in 2 places in the code now.

This represents some significant work on the ALT1 fitter. It is
still being tuned, but seems to be working at a level that
makes it a reasonable place to commit and save in the repository.
Among the changes:

- Added FDC layer to layer correlations. This included
 o Added fdc_correlations.cc file (should be made into a class later)
 o Added GetResiInfo methods and modified Chisq methods to use them.
   This merges how the errors are used to make the matrices used
   for the fit and the matrices used to calculate the chisq into
   a single place.
 o Added cov_meas, cov_muls, and weights matrices to DTrackFitterAlt1
   class to hold the covariance and weights from the last
   call to one of the Chisq() methods

- Catch several errors earlier to avoid error messages. This
  includes some about Nswim_steps=0.

- Renamed the GetWiresShiftsErrors() method to the more appropriate
  GetHits()

- Removed numerous obsolete configuration parameters. Many of these
  were related to hit selection that was moved off some time
  ago into the DTrackHitSelector class.

from target and use it as guess for the second iteration.
