Class Description

 JSRSFQuickSim

 Quick simulator for JLC detector.
 This version calls Quick simulator written by Fortran, which is
 those in lclib, then detector informations are outpu a la C++ class.

 When Quick Simulator is executed, detector information are saved in
 JSFQuickSimBuf class, where pointers to detector signals are prepared.
 The JSFQuickSimBuf includes following information:
    CDC track information, VTX/EMC/HDC hit information,
    LTKCL information ( created by combining CDC and EMC/HDC information)

 There are several link information among classes.  Thoese are
    JSFLTKCLTrack.fCDC -> JSFCDCTrack  ( only for charged track.)
    JSFCDCTrack.f1stCDC -> index of JSFCDCTrack in JSFQuickSimBuf.fCDCTracks
    JSFCDCTrack.fVTXHits[i]  -> JSFVTXHit
    JSFCDCTrack.fGenID  -> (index of JSFGeneratorParticle + 1 )
    JSFVTXHit.fLinkedTrack ->index of JSFCDCTrack in JSFQuickSimBuf.fCDCTracks
    JSFVTXHit.fGenTrack ->(index of JSFGeneratorParticle + 1 )

 For simple minded usage, the use of LTKCL information is recomended,
 as it includes both Track and Calorimeter information.  For example to
 calculate total energy from LTKCL is as follows.

   JSFQuickSim *sim=(JSFQuickSim*)gJSF->FindModule("JSFQuickSim");
   JSFQuickSimBuf *sbuf=(JSFQuickSimBuf*)sim->EventBuf();
   TClonesArray *cmbt=sbuf->GetTracks();
   TVector psum(4);
   for(Int_t i=0;i<sbuf->GetNTracks();i++){
     JSSFLTKCLTrack *lt=(JSFLTKCLTrack*)sbuf->UncheckedAt(i);
     TVecor pv(4);
     pv=lt->GetPv();
     psum=psum+pv;
   }
   printf(" Total energy is %gn",psum(0));


  Environment parameter and its default value  are as follows

 # If 0, track parameter in JSFCDCTrack is parameter by CDCTrack only.
 # If 1, JSFCDCTrack is a result of CDC-VTX combined track parameter.
  JSFQuickSim.CDCTrackIsCDCVTX   1

 JLC QuickSimulator module.

 Simulate one event.

 Copy Generator Particle information in the GeneratorParticles class
 into the TBS bank.
 All generator particle information stored in JSFGenerator class is
 saved in TBS's bank, Generator:Particle_List.  All objects in the
 TClonesArray are copied according to the order save there.

  JSFModule::MakeBranch(tree);

  Set Branch address for this module

  Generator information of particles with finite decay length is revised
  by swim routine.  JSFGenerator class information is updated according to the
  updated Generator:Particle_List informations.
