	  https://github.com/banksean wrapped Makoto Matsumoto and Takuji Nishimura's code in a namespace
	  so it's better encapsulated. Now you can have multiple random number generators
	  and they won't stomp all over eachother's state.

	  If you want to use this as a substitute for Math.random(), use the random()
	  method like so:

	  var m = new MersenneTwister();
	  var randomNumber = m.random();

	  You can also call the other genrand_{foo}() methods on the instance.

	  If you want to use a specific seed in order to get a repeatable random
	  sequence, pass an integer into the constructor:

	  var m = new MersenneTwister(123);

	  and that will always produce the same random sequence.
