WHAT IS THIS PROGRAM?
This program is used to find Mersenne Prime numbers. See
https://primes.utm.edu/mersenne/index.html for a good
description of Mersenne primes. Mersenne numbers can be proved
composite (not prime) by either finding a factor or by running
a PRP (PRobable Prime) or Lucas-Lehmer primality test.
