        model is not created at initialisation time.
    + Low Energy:
      o Suppressed exception warning issued by some Penelope models;
        Controlled by verbosity flag now for diagnostics.
      o Allow for (AutoLock-protected) creation on-the-fly of tables in
        SampleSecondaries(); avoid crash when the loop of SampleSecondaries()
        is inkoved in a unit test.
      o Fixed Coverity report in G4LivermorePhotoElectricModel.
    + Standard:
      o Bug fix in G4UrbanMscModel; 1st normal step in StepLimitType 2 mode

        Reduced number of divisions by addition of extra class members.
      o G4NuclearStopping: fix to avoid changing ion charge.
      o G4ionIonisation: do not instantiate extra model at high enegry if
        G4IonParameterisedModel is used. Improved printout at initialisation.
      o G4SauterGavrilaAngularDistribution: use Penelope 2008 sampling
        algorithm, as it is more effective; distribution itself is unchanged.
      o G4GoudsmitSaundersonMscModel, G4GoudsmitSaundersonTable: use G4Log(),
        and G4Exp().
      o G4eCoulombScatteringModel, G4eSingleCoulombScatteringModel: get pointer
        to the vector of cuts from parameters of Initialise(..) method and not
        from G4ProductionCutsTable; more convenient for unit tests.

        with charge zero.

        in one job (affecting muons and e- and providing non-reproducibility)
      o G4LossTableMananger, G4EmProcessOptions: define default verbosity=0
        for worker thread, so summary on EM processes is not duplicated.
      o G4VEnergyLossProcess, G4VEmProcess: define fixed precison=6 for
        initialisation printout.
    + xrays:
      o Make some class members and methods static in G4Cerenkov and

      o G4BinaryLightIonReaction: fix for Coverity report on small leak.
      o Added printout of particle name in check for valid type of projectile 
        in G4BinaryCasacde::ApplyYourself().
    + models/de_excitation:
      o G4ExcitationHandler: fixed minor memory leak in the case when
        FermiBreakUp has no final states available; reported in item
        #1371 in hypernews Hadronic forum.
      o G4NuclearLevelManager: trivial fix for defect reported by Coverity.
