class RPoisson extends RandomDeviate

Random deviate from the poisson distribution based on the GSL implementation. File poisson.c Line 26. gsl_ran_gamma

The poisson distribution has the form

p(n) = (mu^n / n!) exp(-mu)

for n = 0, 1, 2, ... . The method used here is the one from Knuth.

The implementation of gsl_ran_poisson is somewhat more concise than that given in the Numerical Recipes.
