/// \details Interface for evaluating a given quenching model for a given
///          particle traversing a given material, adhering to interface
///          necessary for e.g. integration methods. Currently, only single
///          -parameter BirksLaw is supported as a model, but this can be
///          abstracted into a generic quenching model.
