Detailed Description

Processes for a single particle type.

Each index should be accessed with type ParticleProcessId. macro_xs stores the cross section tables for each process, while energy_loss and range are the process-integrated dE/dx and range for the particle. integral_xs will only be assigned if the integral approach is used and the particle has continuous-discrete processes.

Todo:

If it's possible for a particle to have multiple at-rest processes, at_rest should be the process with the smallest lifetime. This is used in select_discrete_interaction to choose the at-rest process with the smallest time to interaction if the particle is stopped and has a process that applies at rest.
