NonnullRefPtr<T> is a special variant of RefPtr with one additional property: it cannot be null. NonnullRefPtr is suitable as a return type from functions that are guaranteed to never return null, and as an argument type where the argument may not be null. In other words, if RefPtr is "\*", then NonnullRefPtr is "&".
Objects can only be held by RefPtr if they meet certain criteria. Specifically, they need to implement the functions `ref()` and `deref()`.

To make a class T reference counted, you can simply make it inherit from RefCounted<T>. This will add all the necessary pieces to T.
