I've got the plan in place:

1. Enumerate all possible combinations of X KB of code.
2. Filter out those that correctly implement the source code.
3. Sort by speed.
4. Pick the fastest.
5. Output the hex file.

The prototype Python code for step 1 is already written, but I'm having 
trouble testing - I think I need more ram in my PC, and maybe a faster 
processor...
