tight prime generator

A small piece of code that generates primes to n, pretty fast too.

Just enter a number for searchlimit in the source code. Then run it. On my old Macbook Pro, it takes only 0.112 seconds to list the primes to 10,000. That's not the fastest possible method, but pretty clean and quick. And easy to read and understand. Handy, and only about ten lines of code including tic and toc.
