This is a runtime-staged compiler that compiles Scala 3 to Simple Planes' Funky Trees. Based on LMS work.

Stages:

1. Scala Macros: Scala program -> Scala program that produces Funky Trees IR
2. Scala Runtime: Program from (1) -> Funky Trees IR
3. IR compilation: IR (2) -> Funky Trees AST
4. Output: AST (3) -> XML, ready to use in the game
