Example: analysis/AnaEx02


1) Example compiles, runs (?)
   yes

2) External software documentation (if present)
   yes  
   Root can be installed without ROOTSYS environment variable set;
   it is better to use root-config in GNUmakefile
   (see the diff below)

3) Classification of classes
   List classes specific to demonstrated features:
   (same as in AnaEx01)

   DetectorConstruction
   DetectorMessenger
   EventAction
   HistoManager
   RunAction
   SteppingAction
   
   List of classes which can be replaced with common ones:
   (same as in AnaEx01)

   ExG4HbookAnalysisManager
   g4hbook_defs
   g4hbook
   PhysicsList
   PrimaryGeneratorAction
   
4) Messenger classes
   List commands defined in this example: 
   (same as in AnaEx01)
   /N03/det/setAbsMat 
   /N03/det/setGapMat 
   /N03/det/setAbsThick
   /N03/det/setGapThick
   /N03/det/setSizeYZ
   /N03/det/setNbOfLayers
   /N03/det/update
   
   List commands which do not work as expected:
   (same as in AnaEx01)
   a) not at all
   -
   
   b) in some G4 phase(s)
   - By default the UI sesion opens in Idle> phase, so one cannot
   test commands in PreInit> without modifying main
   - when /N03/det/setAbs/GapMat fails (material not found) user is not 
     notified about failure:
     /N03/det/setAbsMat Al
   
5) Code review:
   Report on obsolete code (if present):
   -
   
   Report on inefficient code (if present):
   -
   
   Your recommendations to example owner:
   (same as in AnaEx01)
   - Use classes from common as suggested in the item 3)
   - Share classes with AnaEx01
   
6) Documentation review:
   Your recommendations to example owner:
   (same as in AnaEx01)
   - The same scenario is now used in basic/B4 example;
    it should be good to comment in the documentation
    what is different here:
    - flexible geometry
    - only one scoring way
    - histo manager    
   
7) Comment on the adequacy in its physics domain
   (skip this item if you are not an expert in physics demonstrated 
   in the example):
   -
   
8) "Users questions to be addressed in examples"   
   List questions which can be naturally addressed in this example:
   (same as in AnaEx01)

   General:
   (2) How to get the runID and eventID?
   (22) How to collect the energy of all shower particles that follow a gamma
          entering a detector, separately for each entering gamma? (maybe)   
   DetectorConstruction:   
   (1) How to modify the geometry during a run?
