 // Class Description:
 //
 // e-/e+ Coulomb scattering model based on numerical Differential Cross Sections
 // (DCS) obtained by Dirac Partial Wave Analysis (DPWA) and supplied by the
 // G4eDPWAElasticDCS class.
 // The model contains the possibility to incorporate the effects of angular
 // deflections of sub-threshold ionisation intercations when it's described by
 // the condensed history model. Note, this must be inactivated (by setting the
 // `isscpcor` input argument of the CTR to false) when ionisation is described
 // with a classical, event by event based simulation model instead of usign the
 // condensed history approach (otherwise, the corresponding angular defelctions
 // will be "double counted").
