Title: Added Memory Clean-up

Added a cascading memory clean-up effect based on panics caused by writing to closed channels.
Usage:
primes := Sieve()
close(primes)
This allows you to create multiple fast prime-number generators without suffering from massive memory problems.
Thanks for writing this in the first place.
