//      ChangeHistory:
//        17-11-2009 creation by L. Desorgher
//        24-11-2009 L.Desorgher,
//           -registering in  Conv* ASCII files every 5000 events the computed
//                edep with  precision.
//           -Correction of the adjoint computed current and answer matrices
//           by a factor n_asked/n_processed for the case where a run is aborted
//          because the user expected precision on e_dep has been reached.
//        7-11-2013 L. Desorgher, migrate to the use of G4Histo
