# == Synopsis
# Calculate the prime numbers less than a given maximum integer.
#
# @example
# choices = {}
# choices[:max_integer] = 20
# sieve = Primes.new(@logger, choices)
# primes = sieve.execute
# # primes => [2,3,5,7,11,13,17,19]
#
# Note, uses the Command design pattern

# @param choices {see SieveOfEratosthenes#Initialize}
