Description

The Sightly script engine should be broken into three modules:

1. a Sightly frontend compiler that interprets Sightly scripts and produces an Abstract Syntax Tree (AST)
2. a Sightly Java backend compiler that interprets the AST and produces Java class files
3. a Compilable Script Engine that reuses the previous two modules
