This is an example that aims to test the treatment of decays in Geant4.
In particular, we want to test the decays of the tau lepton, charmed and
bottom hadrons, and the use of pre-assigned decays.
Note that pre-assigned decays are decays that are usually specified by
Monte Carlo event generators. For simplicity, and to avoid dependencies
on external code, in this test we don't use any MC generator, and we
pre-assign decays by hand (using the Geant4 decay table: this is done
in the method SteppingAction::UserSteppingAction). But this does not
change anything regarding the testing of the pre-assignment mechanism
of Geant4.
