Public Member Functions
	gaussianGeneratorOp (const label seed=Random::defaultSeed)
	Default construct or with seed value. Uses default [0,1] interval.
T	operator() ()
	Generate a random number.
template<class U>
T	operator() (const U &) const
	Ignore parameter and generate a random number, which allows it to be used as a replacement for general unary operators.
