0011 // A simple track structure for e-/e+ particles.
0012 //
0013 // A G4HepEmElectronTrack contains several extra information beyond those base
0014 // properties that are already available in the NEUTRAL G4HepEmTrack object.
0015 // Such G4HepEmElectronTrack object buffers are stored in each G4HepEmTLData
0016 // object, that are unique for each worker, to propagate and communicate
0017 // primary/secondary e-/e+ track information between the different phases of a
0018 // given step or between the G4HepEmElectron/GammaManager and their functions.
