15 * Basic Linear Congruential Generator. This is one of the simplest and
16 * most common pseudo-random number generators out there. It's simple,
17 * fast, and does a decent job if you don't have any stastistical
18 * requirements other than "random looking." This is the algorithm included
19 * as the default random number generator in most standard libraries,
20 * although this one uses larger numbers internally, has a longer period,
21 * and more even distrubition of randomness accross it's bits than most
22 * implementations.
23 *
24 * The base values were published by Donald Knuth.
