/*! \page ExampleAnaEx03 Example AnaEx03

 Example AnaEx03 demonstrates usage of analysis commands for file management
 (new since Geant4 11.1), in particular writing histograms and ntuples in a file
 multiple times, and commands for histogram deleting (new since Geant4 11.2).

 It uses the same scenario (detector description, primary generator
 and physics) as \link ExampleAnaEx01 AnaEx01 \endlink and \link ExampleAnaEx02 AnaEx02 \endlink.
 In difference from these examples
 the analysis manipulations (histograms and ntuples booking and filling)
 are performed directly with G4AnalysisManager. The classes that are same
 in all three examples are located in shared directory.

 For detector description, primary generator, physics and the example output
 see \link ExampleAnaEx01 README in AnaEx01 \endlink example.

 \section AnaEx03_s1 Histograms, Ntuple:

 The example produces the same 4 histograms and 2 ntuples as in AnaEx01.

 These histos and ntuples are booked in the RunAction constructor and filled from
 EventAction.

 The file managent in this example, usually performed via calls to G4AnalysisManager
 OpenFile(), Write() and CloseFile() in the code, is in this example performed
 via UI commands in a macro:
\verbatim
/analysis/openFile
/analysis/write
/analysis/closeFile
\endverbatim

 Note that the file does not need to be closed at each end of run and the histograms and ntuples
 can be saved in the same file multiple time. In that case we need to reset the histograms
 and ntuples data before a new run:
\verbatim
/analysis/reset
\endverbatim

 We can define the default file type and set it to the analysis manager via
\verbatim
/analysis/setDefaultFileType root    # or csv hdf5 xml
\endverbatim

 The file names then need not to be provided with the file extension and the same macro
 can be used with different output types.

 To demonstrate UI commands for deleting of selected histograms:
\verbatim
/analysis/h1/delete id [keepSetting]
\endverbatim
 two H1 histograms, id: 1 and 3, are deleted in AnaEx03.in macro before starting Run 2,
 and new histograms are then created before starting Run3. New histograms are created at
 id's liberated with previous deleting, 1 and 3.

 It should be notes that using UI commands for writing histograms and ntuples in a file
 multiple times is not necessary, the same can be achieved by calls to G4AnalysisManager
 functions from the code using conditional statements.

 \section AnaEx03_s2 Macros

 - The AnaEx03.in macro performs 5 runs and produces 2 files: e-.root, containg data from first
 3 runs, and proton.root, containing data from the next 2 runs.
 The macro uses the defaultFileType parameter (alias), which default value, "root" is
 defined in main.

 - AnaEx03-csv.in, AnaEx03-hdf5.in, AnaEx03-root.in, AnaEx03-xml.in:
   In these macros, the default value of the defaultFileType is overritten with
\verbatim
/control/alias defaultFileType cvs   # or hdf5 root xml
\endverbatim
   and then the AnaEx03.in macro is called.


 \section AnaEx03_s3 How to run

 - It is preferable to execute the exampole in the 'batch' mode from macro files:
\verbatim
% ./AnaEx03 AnaEx03.in
% ./AnaEx03 AnaEx03.in >& output
\endverbatim

 - When executing AnaEx03 in the 'interactive mode' with visualization, be careful not
   to forget to issue the /analysis/openFile command befor starting a run:
\verbatim
% ./AnaEx03
and type in the commands from AnaEx03[-xyz].mac line by line:
   Idle> /analysis/openFile myFile
   Idle> /tracking/verbose 1
   Idle> /run/beamOn 10
   Idle> ...
   Idle> /analysis/write
   Idle> /analysis/closeFile
   ....
   Idle> exit
\endverbatim

All AnaEx03-*.in macros are used in Geant4 testing.
