/// \brief Implementation of the TSPhysicsList class
//
//
//
//
/// This is a very, very extensive physics list and step-limiters are applied
///     to many particles. The reasoning behind this is because we wan't to put
///     as much pressure on the atomics as possible and produce as much
///     round-off error as possible. See descriptions in README and
///     TSDetectorConstruction for more details.
