Uniform and Normal Random Number Generator Shootout

I'm sorry, the quality tests are garbage. Anyone who's done even a cursory amount of research into PRNGs has already heard about the Diehard tests and would have used these in preference, or as a subset, of subsequent testing.

As may be expected Diehard isn't the be-all-and-end-all of random generator testing; NIST have their own standards. Dieharder is an attempt to consolidate Diehard, NIST, and various other randomness tests.

This is a severe, severe case of "Not Invented Here"; please do research before reinventing the wheel.
