Expand the test suite with more real-world-ish projects #304
Description
Most of the projects in the test suite are very small. About the most complex thing in there is quicksort. It would be ideal if we had a bigger variety of projects.
Considering that our tests run with no renderer, no pen, no storage, etc. we can't get full projects in here, but we can still extract out the core algorithms of some popular technical projects and include a simple script to make sure that it outputs the right thing for some input.
