MersenneTwisterEngine

The Mersenne Twister generator, developed by Makoto Matsumoto and Takuji Nishimura (1997), allows for fast generation of high-quality pseudorandom numbers, and is widely used as a default random number generator by many programming languages, including D. The current implementation is adapted from that of Boost.Random and supports both 32- and 64-bit datatypes.
