Returns a random number. The Random number generator uses the Mersenne Twister by Matsumoto and Nishimura. It sets new standards for the period, quality and speed of random number generators. The incredible period is 219937 - 1, a number with about 6000 digits. The 32-bit random numbers exhibit best possible equidistribution properties in dimensions up to 623 and it's fast, very fast.
