class XORShiftRandom extends Random

XORShiftRandom

copy from spark framework

This class implements a XORShift random number generator algorithm Source: Marsaglia, G. (2003). Xorshift RNGs. Journal of Statistical Software, Vol. 8, Issue 14. http://www.jstatsoft.org/v08/i14/paper This implementation is approximately 3.5 times faster than java.util.Random, partly because of the algorithm, but also due to renouncing thread safety. JDK's implementation uses an AtomicLong seed, this class uses a regular Long. We can forgo thread safety since we use a new instance of the RNG for each thread.
