-/* Random Number Generator Tests
-   There can be meny more tests on quality of the
-   random number generator.  For now we are only
-   testing the frequency of particular bits.
-   We could also test consecutive sequences,
-   randomness within a particular block, etc.
-   but is probably not necessary for our purposes */
