0027 /// \brief Implementation of the TSPhysicsList class
0028 ///
0029 /// This is a very, very extensive physics list and step-limiters are applied
0030 ///     to many particles. The reasoning behind this is because we wan't to put
0031 ///     as much pressure on the atomics as possible and produce as much
0032 ///     round-off error as possible. See descriptions in README and
0033 ///     TSDetectorConstruction for more details.
