Notes: - Minimal random number generator of Park and Miller with
         Bays-Durham shuffle and added safeguards.

       - 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.
         There are no statistical tests known that it fails to pass, execpt
         when the number of calls starts to become on the order of the period.
    When you need longer random sequences you should use
         another random generator, for example Ran002 or Ran013.

       - At least 32 bit long int is required, but works with any larger
    word lengths
