Detailed Description

A uniform random number generator.

This is a congruential uniform generator which draw double between 0 and 1 excluding the end points. This generator is based on a Fortan routine from Wichmann, B. A. and Hill, I. D. (1982). "An efficient and portable pseudorandom number generator," Applied Statistics, 31, 188-190
