* `arc` feature to make engine usable from multiple threads. `arc` is turned on by default. When enabled, std::sync::Arc will be used instead of std::rc::Rc. The former makes regorus types like Engine, Value, ast nodes etc Send, allowing for usability from multiple threads. Arc would add a performance overhead though since the reference counting will now become atomic.
