Compute the value of pi via dart throwing!

	for i in 1...zillion
		throw a dart randomly and uniformly over the unit square
		compute it's distance from the center
		if distance < 0.5
			hits++
		total++
	print "Pi = " hits / total * 4


Using multiple threads, make this program faster!

What to turn in:
		Code
		how long it took to run with 1,2,4 and 8 threads

Note:  To get good thread safe random numbers do this

import java.util.concurrent.ThreadLocalRandom;

public class it {
        public static void main(String args[])
        {
                double r = someDouble = ThreadLocalRandom.current().nextDouble(0, 1);
                System.out.println("R = " + r);
        }
}
