Indicate that a CAD-based DAGMC geometry will be used.

Indicate whether to scale the fission photon yield by (EGP + EGD)/EGP
where EGP is the energy release of prompt photons and EGD is the energy
release of delayed photons.
electron_treatment : {'led', 'ttb'}
Whether to deposit all energy from electrons locally ('led') or create
secondary bremsstrahlung photons ('ttb').
