Added bytecodes for comparing integers. Added BoolBox type for boxed booleans. Added debug switch so interpreter can be run on CPython. Added some inline documentation and TODO comments. Still to do - turn bytecodes into integers, refactor long lists of methods and ifelse blocks, improve error checking.
Factored boxed types into their own file.
Added simple test for ==
Opcodes now integers, stored as a dictionary. Parser now parses ascii .cspc files into numeric opodes. Consts / literals are all stored in separate lists to satisfy the type checker.
