Runnable examples (#576)
Provides a basic interface for running examples on tweaked.cc. This is probably
janky as anything, but it works on my machine.

This is the culmination of 18 months of me building far too much infrastructure
(copy-cat, illuaminate), so that's nice I guess.

I should probably get out more.
