A lognormal_distribution random number distribution produces random numbers x > 0 distributed according to the probability density function

explicit lognormal_distribution(RealType m = 0.0, RealType s = 1.0);
Requires: 0 < s .
Effects: Constructs a lognormal_distribution object; m and s correspond to the respective parameters of the distribution.
Returns: The value of the m parameter with which the object was constructed.
Returns: The value of the s parameter with which the object was constructed.
