Prime Multiplication

An application that generates multiplication tables of prime numbers.

The prime number generator is intentionally simple (increment, use unoptimised trial division for primality test).

But it's built using asynchronous streams, which means it works well on the web and on the command line with zero memory footprint and no buffering.

My focus is to demo an actual service, not to improve the sieve of Eratosthenes.
