Added extra Physics Lists for neutron background study

[civanch]

For neutron background study 3 new Physics Lists are added: FTFP_BERT_HP_EMM, FTFP_INCLXX_EMM, and FTFP_INCLXX_HP_EMM. Should not affect mainstream production.

A new Pull Request was created by @civanch (Vladimir Ivantchenko) for master.

It involves the following packages:

SimG4Core/PhysicsLists

@cmsbuild, @civanch, @mdhildreth can you please review it and eventually sign? Thanks.
@makortel this is something you requested to watch as well.
@davidlange6, @slava77, @fabiocos you are the release manager for this.

This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @davidlange6, @slava77, @smuzaffar, @fabiocos (and backports should be raised in the release meeting by the corresponding L2)

[fabiocos]

@civanch were these lists minimally tested in a standalone way? Obviously this PR test just shows they compile...

[civanch]

@fabiocos , they are tested by Geant4 team - no extra hadronic component is added from us, EMM is our production variant for electromagnetic physics. FTFP_BERT_HP is the Geant4 default for high precision neutrons, we already have FTFP_BERT_HP_EML, now FTFP_BERT_HP_EMM is added. All these is well tested.
FTFP_INCLXX and FTFP_INCLXX_HP are used not so frequently and there are known advantages and concerns to use INCLXX cascade model. In past, I tried to avoid include them as CMSSW options but Sergio several times ask about such possibility for neutron background study. I think, that if a physics list is available in Geant4 distribution, then we can provide a possibility to CMS users try it out if there is a request.

[fabiocos]

@civanch in between the detailed physics validation done by Geant4 (of the model but not of the CMSSW interface proposed here) and that can be redone once this code is available, and the mere fact that this code compiles, there is a cmsRun with a modified physics list showing that this code runs on some events without crashing/doing anything odd. Was this done by you? I assume yes, I just would like to have a confirmation about it.

[civanch]

@fabiocos , I run 100 MinBias events for each Physics LIst - no problem observed , except the fact that all these new Physics Lists are substantially slower the CMS default, but this is expected.

[fabiocos]

@civanch ok thanks
