public class RandomShuffle
extends RandomElement

RandomShuffle uses one random number generator to shuffle the numbers produced by another to obliterate sequential correlations. To initialize a RandomShuffle, pass it two RandomElements. The first RandomElement is used to generate a table of random numbers and the second is used to choose one from the table. An example of usage is,

RandomElement markov=new RandomShuffle(new Ranecu(),new Ranmar(),32)

which would generate a deck of 32 numbers from RANECU and use RANMAR to choose from the deck.
