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

 Set link information of JSFLTKCLTracks

 Copy Production:Combined track banks into JSFLTKCLTrack class

 Create JSFEMCHits and JSFHDCHits from
 the TBS bank, Production:EMC;Hit_Cell and Production:HDC;Hit_Cell

 Create JSFVTXHits class
 the TBS bank, Production:VTX;Hit and Production:VTX;Hit_Errors
 Using the tracks saved in JSFCDCTrack class, VTX hits are obtained
 from Production:VTX;Hit and Production:VTX;Hit_Errors bank,
 and saved in JSFVTXHit class.

 Create JSFCDCTracks class.
 The track parameters in the TBS bank,
 Production:CDC_VTX;Track_Parameter is saved as data member.
(Warning)
 Only tracks which has entry in JSFLTKCLClass is saved in this class.

 After reading the class data for JSFQuickSimBuf, pointers
 for JSFCDCTracks and JSFVTXHits are reset.

 Append JSFQuickSimBuf object, src, to current object
 numgp is a number of generator particles in the src.  It is used to increment
 pointer information to JSFGenerator objects
 gbuf: is a pointer to newly created JSFGeneratorBuf class.

 Append JSFQuickSimBuf object, src, to current object
 src  : A pointer to source JSFQuickSimBuf object.
 numgp: Number of generator particles added.
 gbuf : A pointer to JSFGeneratorBuf where generator information is added.
