This is hopefully going to make navigating the source tree easier. Hopefully. The only types that don't get their own files are: * function types (UserFunction, BuiltinFunction, Method), which all live in obj/function.rs * Nil, which lives in obj.rs * Obj, which lives in obj.rs Type definitions and init_types now live in obj/ty.rs. New obj::prelude module for common imports. Signed-off-by: Alek Ratzloff <alekratz@gmail.com>
