Notes: - NOT RECOMENDED FOR SERIOUS APPLICATIONS.
    Just use it for comparison purposes, etc.

       - This generator is fast

       - "Minimal" random number generator of Park and Miller.
        x(n) = 16807 * x(n-1) mod (2^31-1)
         also known as GGL.

  - Set seed to any integer value (except the unlikely value mask) to
    initialize the sequence.

       - The period is 2^31-2 = 2.1*10^9. If your application needs
    more numbers in sequence than 1% of the random generators period,
    i.e. 10^7, then use a more elaborate random generator.

       - At least 32 bit long int is required.
