8  * COMMENTS:
9  * void UT_fastRandomSeed(int seed)
10  * Seed the fast random number generator
11  *
12  * fpreal UT_fastRandom(void)
13  * Really, really fast random number generation - pretty good
14  * distribution of sequential random numbers
15  *
16  * Ref. Numerical Recipes (pp 284)
17  *
18  * Currently, only the fast random number generation is included
19  * here, however, in the future, there may be other utilities.
