Detailed Description

Transportation for the monopole species only.

These must be true for the monopoles and false for every other particle:

the field manager of the current volume (the global one, or a local one) has to use the monopole chord finder, otherwise O2MonopoleEquation might not be evaluated at all (such as it happens with the default NystromRK4)
G4Transportation has to consider the magnetic moment
the field manager has to declare that the field changes the energy: the g*B force does work on the monopole. Otherwise G4Transportation would reset the kinetic energy at the end of every step to the one at its start, keeping only the change of direction

Ordinary tracks keep the stepper the run was configured with, and neutral particles that happen to carry a magnetic moment (neutrons above all) keep their straight-line transport.

This mirrors G4MonopoleTransportation from the Geant4 monopole example, which takes the kinetic energy and the time of flight from the integrated track, but derives directly from G4Transportation, so that it follows the Geant4 versions
