 Create list to support list of particles

 Create list to support list of particles

    Delete graphics temporary objects

    Dummy

 scan list of particles

    Estimate step size in function of field.
    Create a 3-D polyline with points computed with this step size

     extrapolate track with parameters in vector vin in a constant field
     oriented along Z axis (in tesla/meters).
     Output in vector vout
     vin[0-->6] = x,y,z,px,py,pz
     translated to C++ from GEANT3 routine GHELX3

    Paint particles generated by ATLFMCMaker
    Only particles above m_PTcut are drawn
    Particle trajectory is computed along an helix in a constant field
