Detailed Description

The struct for the EnergyLoss physics list.

This generates the energy loss according to the Bethe-Bloch description, applying a landau generated enery loss

It follows the interface of EnergyLoss samplers in Fatras that could return radiated photons for further processing, however, for the Bethe-Bloch application the return vector is always 0.
