27 October 2010 Gabriele Cosmo (tracking-V09-03-08)
- Restored DLL setup as originally. Withdrawn changes in last tag.

19 October 2010 Gabriele Cosmo (tracking-V09-03-07)
- Replaced G4TRACKING_ALLOC_EXPORT flag with G4ALLOC_EXPORT for DLL exported
  symbols.

- Modified G4SteppingManager::GetSecondary() to give const G4TrackVector* 
  (co-work with track-V09-03-05)

19 July 2010 Gabriele Cosmo (tracking-V09-03-05)
- Added dummy initialisation to members in constructors in classes:
  G4AdjointSteppingAction, G4UserSteppingAction, G4UserTrackingAction
  and G4VSteppingVerbose.
- G4SteppingManager:  and use canonical form for G4Exception.
  Added protection for possible negative index in method ApplyProductionCut()
  and some printout formatting.
- Added redundant return statement after exception in G4SteppingManager2.
- Fixed restoring of output settings in G4SteppingVerbose.
- Use 0 instead of NULL where applicable.

16 June 2010 John Allison (tracking-V09-03-04)
- G4VTrajectory, G4Trajectory, G4SmoothTrajectory:
  o Reverted to original interface: DrawTrajectory(G4int i_mode = 0).
    This to prevent compiler warnings about hiding.  We will
    re-instate DrawTrajectory() at a future major release.
  o Deprecation message is printed via G4Exception only once, and only
    if a user invokes with a non-zero value of i_mode.

29 May 2010 John Allison (tracking-V09-03-03)
- G4VTrajectory:
  o Added virtual void DrawTrajectory() in preparation for i_mode migration.
- G4Trajectory and G4SmoothTrajectory: followed the above.
  o (G4RichTrajectory inherits G4Trajectory so no need to change.)

28 May 2010 John Allison (tracking-V09-03-02)
- G4VTrajectory.cc: Added explicit once-only i_mode deprecation warning.

13 May 2010 John Allison (tracking-V09-03-01 - needs greps-V09-03-00)
- G4VTrajectory.cc: Added a statement to set IsDefaultDrawTrajectory,
  to assist deprecation of i-mode trajectory drawing parameter.  After
  10.0, it can be removed.

22 Feb 2010 John Allison (tracking-V09-03-00)
- G4RichTrajectory: Fixed bug in MergeTrajectory (should not invoke
  G4Trajectory::MergeTrajectory).
- G4RichTrajectory and G4RichTrajectoryPoint:
  o Eliminated spaces in G4AttValue values.
  o G4AttValue values are "None" for attributes derived from zero pointers.

20 Nov 2009 L.Desorgher (tracking-V09-02-06)
- Small correction in G4AdjointSteppingAction to stop the reverse tracking
  when adjoint particles reenter the adjoint source. 
  Reput the Nan test removed in  tracking-V09-02-05 but now as (x<0 && x>=0).
  This Nan test is still needed in very rare case where the weight of a
  particle goes to Nan. As such the code is stable! The reason for the Nan
  weight is till under investigation.

18 Nov 2009 G.Cosmo (tracking-V09-02-05)
- Fixes to "Adjoint" classes to allow build of DLLs on Windows: renamed all
  methods and data holding "External" as keyword to "Ext".
  Cleanup of the code: use "const G4String&" instead of "G4String" wherever
  possible; use G4 types in consistent way; avoid usage of "isNan"; code
  formatting cleanup; added Geant4 disclaimer.

12 Nov 2009 J.Allison (tracking-V09-02-04)
- G4Trajectory, G4SmoothTrajectory, G4RichTrajectory:

- Tag for tracking-00-07-02. This includes the following features.
- Because J. Apostolakis changed  the way to calcluate safety in the 
  transportation AlongStepGPIL, the way to set safety of the PostStepPoint
  was modified. Except the first step, the safety of the PreStepPoint
  is also valid in this scheme.
- The coherent energy cut scheme is implemented. This means that 
  the energy of a secondary particle is checked against the energy
  cut value and also safety. Also the 'GoodForTracking' flag is 
  checked. A warning message will be issued if a secondary particle
  has illegal status (i.e. below energy cut and 'GoodForTracking' is off).
  Because processes don't set properly the 'GoodForTracking' yet, this
  waning message is temporary suppressed in the current tag.

- Added fix to implementation of new scheme of 'Safety'.

June 16, 98 P.Urban                      -- recorded by J. Apostolakis

- Added changes for tracking optimisation.  (Merged from branch)
- tagged tracking-00-06-03.

- Tagged tracking-00-06-02.
  Includes changes by P.Mora de Freitas and M.Asai which were missing in
  the previous tag.

June 6, 98  M.Asai
- GNUmakefile is modified to correspond to the new "digits+hits" structure.

Jun  3, 98  P.Mora de Freitas/M.Verderi
- Implement new scheme of 'Safety' where it becomes the 'range within 
  the assumptions of all processes are valid'. In the G4SteppingManager
  GetPIL loop the safety becomes "competitive" like the step limitation. 
  This means that at the begining of every step the G4SteppingManager 
  will initialize it to DBLMAX and that processes can only decrease it.

May 22, 98  T.Sasaki
- Verbose codes are separated from SteppingManager. 2 files are aded.
April 21, 98 G.Cosmo (tracking-00-05-01)
- Tagged.

April 12, 98 H.Kuraashige
- Implement new scheme of 'Particle Change'. Please see 
  particle_change.asc in geant4alpha/documents/particles+matter/.
  G4SteppingManager.hh,  .cc have been modified.

April 9, 98 G.Cosmo
- Porting on DEC-cxx 6.0.
  Removed meaningless usage of "const" qualifier from functions
  return type for basic types by value. Modified files: G4Trajectory.hh

  Add following information to G4Track: 
     1.Momentum direction at the start point (vertex position) of the track 
     2.Kinetic energy at the start point (vertex position) of the track 
     3.Pointer to the process which created the current track 
  Due to this, the following files have modififed and committed.
     1.NewDesignDoc.txt 
     2.G4Track.hh, G4Track.cc 
     3.G4SteppingManager.cc

  Following changes have been done and committed/tagged to cvs.
  Tag# is tracking-00-03-01. 
    - G4SteppingManager.cc: Corrected so that the verbose 
      'AlongStepDoItAllDone' is invokded after the 'safety' update.
    - G4SteppingManager.cc: Added a comment in the 'G4Step Information' 
      table of the verbose output of 'AlongStepDoIt (process by process)' 
      so that 'safety' value in it is not updated yet.
    - G4TrackingMessanger.cc: Help for verbose has been updated.

- Created.
