Sieve of Eratosthenes
/*jshint esnext: true */
/*
https://en.wikipedia.org/wiki/Sieve_of_Eratosthenes
1. Create a list of consecutive integers from 2 through n: (2, 3, 4, ..., n).
2. Initially, let p equal 2, the smallest prime number.
3. Enumerate the multiples of p by counting to n from 2p in increments of p, and mark them in the list (these will be 2p, 3p, 4p, ...; the p itself should not be marked).
