// -----------------------------------------------------------------------
// Class defining methods RandGaussT, which is derived from RandGauss.
// The user interface is identical.
// RandGaussT ---
// Always uses exactly one flat random from the engine
// Is stateless so that saveEngineStatus works even if invoked knowing
// only that the distribution is a HepRandom. (RandGauss is not stateless.)
// Is accurate to more than 12 decimal places in all cases, and more so
// near the end points.
// Runs about as fast as RandGauss.
// RandGaussT utilizes HepStat::flatToGaussian(r), so its effective footprint
// (for the tables used) is almost 30K bytes.
