Probably not. I've written them some time ago, as they are pretty
trivial, but I haven't gotten around to thoroughly test them and change
the tutorials to use them.

It's a simple straight smart ptr. On assigning a value to it increases
the new object's refcount and decreases the current object's refcount.
Of course, only if they're not NullFC. It gives you a cast operator to
the stored pointer type, and the usual -> operator. And that's about it.
The actual work is done by the existing refcount mechanism, which
deletes objects whose refcount goes to or below 0.
The code is really trivial, but you're welcome to take a look and tell
me if there's a loophole for undefined behavior that I missed.
