Detailed Description

Processes for a single particle type.

Each index should be accessed with type ParticleProcessId. The "tables" are a fixed-size number of ItemRange references to ValueTables. The first index of the table (hard-coded) corresponds to ValueGridType; the second index is a ParticleProcessId. So the cross sections for ParticleProcessId{2} would be

tables[ValueGridType::macro_xs][2] 

. This awkward access is encapsulated by the PhysicsTrackView. integral_xs will only be assigned if the integral approach is used and the particle has continuous-discrete processes.
