Below is the output of 'ent' (see http://www.fourmilab.ch/random/) on
  the file "testRng.out" as generated by testRng.

  The output shows that libecc::rng appears to be totally random.

Entropy = 1.000000 bits per bit.

Optimum compression would reduce the size
of this 512000000 bit file by 0 percent.

Chi square distribution for 512000000 samples is 0.76, and randomly
would exceed this value 50.00 percent of the times.

Arithmetic mean value of data bits is 0.5000 (0.5 = random).
Monte Carlo value for Pi is 3.142115071 (error 0.02 percent).
Serial correlation coefficient is -0.000028 (totally uncorrelated = 0.0).
