Instruction

- Made the `toString()` method non-final
- Implemented `produceToStrEnclose(string)` which will create the wrapper `[Instruction: <classNameHere>: <addInfo>]` where `<addinfo>` is the string parameter passed in

LiteralValue

- Implemented custom `toString()` - this will fix the whole updating opf types issue
