/**
 * Given any pair of positive integers chosen from a large set of
 * random numbers, the probability that the two integers have 
 * no common factor other than one is 6/pi^2.
 * This program uses the IntegerList class. It reads in a list of 
 * n distinct integers and computes the estimate value for pi.
