I read the bug template but I'm unsure its relevant for a gap in documentation

I couldn't see any examples or documentation on how to use clone() for a YMap. It produces another YMap instance that I can't interact with until its "included in a doc", but I've no idea how I would go about that. There isn't a setMap or include function that I can see. Do you have an example of how I might go about this?
