1) ISSUE970:  Support for digitization in ddsim

2) ISSUE1103: Allow isotrope generator to throw range around specified (reference) direction: Waiting for user
3)  ISSUE1199: Persist hepmc vertex status code into output
                      ==> Should we eliminate Geant4EventReaderHepMC
                      ==> Decision: Geant4EventReaderHepMC will be removed
4)  ISSUE1200: Using rotation in DDCAD to rotate around z axis 
                      ==> Should be a non-issue (?)
5) ISSUE1233: Protect against wrong primary particle mass enhancement 

6) PR1240:     Add multithreading support to ddsim 
7) PR1252:     Fix usage of podio pre-processor version checks.
