                    Example B4 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.

- Added a protection when /run/printProgress value is set to zero 

30/10/13 I. Hrivnacova (exampleB4-V09-06-15)
- Updated README

29/10/13 I. Hrivnacova (exampleB4-V09-06-14)
- Fixed macro (using /run/printProgress)

29/10/13 I. Hrivnacova (exampleB4-V09-06-13)
- Using G4GlobalMagFieldMessenger
- Using G4Exception for warnings and error messages
- Using G4RunManager::SetPrintProgress()
- Using Gent4 default number of threads when not set via command line
- Updated README

01/10/13 I. Hrivnacova (exampleB4-V09-06-12) 
- Updated for changes in analysis:
  removal of G4AnalysisManager::Create(isMaster)

19/08/13 I. Hrivnacova (exampleB4-V09-06-11)
- Fixed B4[b]RunAction::EndOfRunAction() again: to get the printed 
  histogram statistics correct

24/07/13 P. Gumplinger (exampleB4-V09-06-10)

- Updated README files for changes for MT

03/06/13 I. Hrivnacova (exampleB4-V09-06-06)
- Moved creating analysis manager and booking histograms & ntuples
  in run action constructor; this makes available /analysis commands

29/05/13 I. Hrivnacova (exampleB4-V09-06-05)
- Fixed detector construction classes:
  Moving creating setMagField command from the constructor in 
  ConstructSDandField(), as the command has to be created per thread,
  and declaring fMagField and fMessenger data members as static 
  G4ThreadLocal

24/04/13 M. Asai (exampleB4-V09-06-04)

- Removed unnecessary includes in run action files
- Minor fixes of coding guidelines 

18/04/13 M. Asai (exampleB4-V09-06-02)
- Migrated to the new G4VUserActionInitialization class.

08/04/13 M. Asai (exampleB4-V09-06-01)
- Fixed the use of thread-local G4Allocator for B4c.

06/04/13 M. Asai (exampleB4-V09-06-00)
- Migrated to multi-threading.

28/02/13 I. Hrivnacova
- When building materials with NistManager
  do not set fromIsotopes argument (which was set to false), 
  as since 9.6 all materials have to be built from isotopes.
  Thanks to V. Ivantchenko for pointing at this.

01/11/12 I. Hrivnacova (exampleB4-V09-05-02)
- Implemented new way of handling program arguments in main()

  - Adding a line using G4AnalysisManager::GetType()
- General changes (see basic/History)

13/01/12 I. Hrivnacova (exampleB4-V09-05-00)
- Fixed compiler warning on windows:
  Allocating the messenger in the DetectorConstruction and EventAction classes

  (to avoid passing 'this' in the initializer list).

14/11/11 I. Hrivnacova 
- The first tagged version of the new B4 example
  (tagged in basic).
