> '''Implement a random number generator based on the XORShift algorithm
> discovered by George Marsaglia. This RNG is observed 4.5 times faster than
> {@link Random} in benchmark, with the cost that abandon thread-safety. So
> it's recommended to create a new {@link XORShiftRandom} for each thread.'''
