"""
The sieve of Sundaram is a simple deterministic algorithm for finding all the
prime numbers up to a specified integer. This function is modified from the
Python example Wikipedia entry wiki/Sieve_of_Sundaram, to give primes to the
nth prime rather than the Wikipedia function that gives primes less than n.
