                    Example B3 History file

This file should be used by the G4 example coordinator to briefly
summarize all major modifications introduced in the code and keep
track of all tags.

- Support same CMake version range as core Geant4

30/06/20 G. Cosmo (exampleB3-V10-06-00)
- Migrated examples to use G4RunManagerFactory, therefore implicitly enabling
  tasking by default in MT builds.

21/11/19 G. Cosmo (exampleB3-V10-05-02)
- Use default MixMax random engine.

30/09/19 I. Hrivnacova (exampleB3-V10-05-01)

- Updated documentation for example B3b

13/11/18 J. Madsen (exampleB3-V10-04-03)

  to demonstrate statistical computations in a basic example

30/10/18 I. Hrivnacova (exampleB3-V10-04-02)
- Removed usage of G4ScoreNtupleWriter;
  will be demonstrated in a new extended analysis example

26/10/18 I. Hrivnacova (exampleB3-V10-04-01)

- Replaced explicit printing of Run ID with /run/printProgress
- Updated README

08/05/18 B. Morgan     (exampleB3-V10-04-00)
- Include G4Types before use of G4MULTITHREADED. For forward
  compatibility with move to #defines over -D for G4 preprocessor
  symbols.

22/12/16 M. Maire      (exampleB3-V10-03-00)
- PhysicsList : register Electromagnetic before RadioactiveDecay


19/11/16 A. Dotti      (exampleB3-V10-02-04)
- explicit set of SD to manager

02/11/16 I. Hrivnacova (exampleB3-V10-02-03)
- Fixed comments for Doxygen
- Removed obsolete B3b/exampleB3.cc

26/09/16 I. Hrivnacova (exampleB3-V10-02-02)
- Updated for renaming G4Parameter in G4Accumulable

- Fixed compiler warning introduced in the previous update

20/05/16 I. Hrivnacova (exampleB3-V10-02-00)

  (this fixes the problem report #1862)
- Removed History files from B3a and B3b

05/11/15 I. Hrivnacova (exampleB3-V10-01-01)
- Splitting example in two variants of merging data:
  -B3a (new) with the code based on G4Parameter
  -B3b (as previous B3) with the code based on G4Run

04/05/15 I. Hrivnacova (exampleB3-V10-01-00)
- Coding guidelines: removed empty lines

29/11/14 I. Hrivnacova
- Use G4endl instead of \n in G4cout;
  this makes each new line in the output on threads preceded with
  G4WTN >

- Finalized modifications in previous tag (01):
  - Removed G4UI_USE/G4VIS_USE tests and init.mac macro (not needed)

  G4IonTable::GetIon(), as the former method becomes obsolete.

13/06/13 mma (exampleB3-V09-06-04)
 Fixes for MT:
- Set sensitive detector via SetSensitiveDetector(..)
- Get hits collection IDs in B3Run::RecordEvent (and not B3Run constructor)
- Add a test for primary generator action in B3RunAction::EndOfRunAction()
  as it does not exist on master

05/06/13 mma (exampleB3-V09-06-03)
- add section about ACTION INITALIZATION to README and .README

01/06/13 mma  (exampleB3-V09-06-02)

  and updated actions classes accordingly.
  README files still need to be updated.

28/02/13 I. Hrivnacova
- When building materials with NistManager
  do not set fromIsotopes argument (which was set to false),
