 31 //
 32 /// This is a very, very extensive physics list and step-limiters are applied
 33 ///     to many particles. The reasoning behind this is because we wan't to put
 34 ///     as much pressure on the atomics as possible and produce as much
 35 ///     round-off error as possible. See descriptions in README and
 36 ///     TSDetectorConstruction for more details.
