alice/event:
============
  7.3.00:
     AliSteppingAction: newly implemented for detecting and
         stopping looping particles:
	 After processing a given number of steps (kCheckNofSteps)
         particle position is compared with the previus one
         - in case the distance is less than kTolerance value
         the verbose mode is switched on, particle is let 
         to process a small number of steps (kMaxNofLoopSteps)
         and then stopped and killed 
     AliSteppingActionMessenger:
         new class; implements command /alTracking/loopVerbose 

  25.10.99:
     AliParticleGun:
       GeneratePrimaryVertex(): when particles are created in 
         the same space point (x,t), they are added to the same
	 primary vertex. 

  28.7.99:
     All classes renamed: Al -> Ali

  28.1.99:
     AlSteppingAction: saving of secondary particles moved tp
       AlTrackingAction => class AlSteppingAction is no longer used,
       but it is kept for future;
     ALSTEPPING options has been removed;
         
  22.1.99:
     AlSteppingAction, AlTrackingAction:
       methods SaveParticle() added: the method in AlSteppingAction
         calls the method from AlTrackingAction;
       ALL (both PRIMARY and SECONDARY) particles are stored now 
       
  11.1.98:       
     New classes:   
     AlTrack:  similar structure as G4Event - collects hits 
       collections for primary track;         	       
     AlTrackingAction: performs similar actions as G4EventManager
       - but on the track level;
     AlTrackingActionMessenger:
       command: /alTracking/verbose  
       
  8.12.98:
     AlStackingAction: added fPrimaryStack (G4TrackStack*) for
       postponning primary particles;
       commented pRootManager->StackNewStage() - should be
       called from AlTrackingAction;    
       
  3.12.98:
     New classes: 
     AlSteppingAction: saves info on generated particles
       (it is ruled by ALSTEPPING option) 
     AlStackingAction: postpones tracking of secondary particles
       till the urgent stack is exhausted
       (it is ruled by ALSTACKING option)
     !! ONLY secondary particles are stored  
       
  5.11.98:
     New class: AlEventActionMessenger
     commands: /alEvent/verbose
               /alEvent/drawTracks
	       
  18.9.98:
     Persistent Event (both for Objectivity and Root) is 
     created in AlEventAction::EndOfEventAction(). 
     
  27.8.98:
     removed RWTValOrderedVector<RWCString> AlHCNames attribute;
     Using the G4VHitsCollection::GetSDName() function for
     getting the type of AlXXXHitsCollections.
     
  18.8.98:
     Category name Events changed to Event;
     options G4ROOT/ODBMS_STORE_HITS renamed to ALICE_ROOT/ODBMS;
     updated for beta01
     
  3.7.98:
     modified for root persistency option (G4ROOT_STORE_HITS);

  26.6.98:
     AlGunParticle:
     changed attributes from aParticleMomentumDir, aEnergy to
     aParticleMomentum; added constructor for creating particle
     with given kinEnergy and momentumDir;
     AlParticleGunMessenger:
     changed /alGun/energy to /alGun/kinEnergy;
     added /alGun/momentum
     
  12.5.98:
     AlEventAction:
     added RWTValOrderedVector<RWCString> AlHCNames attribute;
     used AlHCNames for looping over all hits collections defined;
     
  11.5.98:
     modified for persistency option (G4ODBMS_STORE_HITS);
     removed the general loop through all event hits collections
     - only ITS hits collections are included now;
     must be generalised again !

  4.5.98:
     Renaming of classes:
     AliceXXX -> AlXXX
     
  30.1.98:  
     new class Alice particle gun:
     redefines the G4ParticleGun, G4ParticleGunMessenger classes
     - enables shooting different particles in one run 
     - classes: AliceParticleGun, AliceGunParticle
