Mauricio Carneiro cd68cc239b Added knuth-shuffle (KS) and randomSubset using KS to MathUtils ... * Knuth-shuffle is a simple, yet effective array permutator (hope this is good english). * added a simple randomSubset that returns a random subset without repeats of any given array with the same probability for every permutation. * added unit tests to both functions		2012-01-03 09:29:46 -05:00
