38 * Seed the random number generater with time() so we don't see the
39 * same sequence every time.

44 * Seed the random number generater with your own seed so can set up
45 * repeatable randomization.

51 * Return a random number between [0.0, 1.0)
52 * @return next "random" number in the "random" sequence
