Celeritas is a new Monte Carlo transport code designed to accelerate scientific discovery in high energy physics by improving detector simulation throughput and energy efficiency using GPUs.
This differentiates between true material compositions associated with the geometry, and "physics" materials which are modified by physics cutoffs inside a region that's applied to a particular volume. The "geometry materials" are equivalent to G4Material, and the "physics material" are the G4MaterialCutsCouple which is what we use in Celeritas (and need to generalize for #907, #983).
