Supporting shared objects, including cycles

I did this as a weekend project. I wouldn't say it's ready to be included yet, but I'm interested in feedback. The README is pretty complete.

@dignifiedquire any next steps?

Never got around it, would be great to figure out how to include this in an efficient and safe manner

Looking over it again, I'd be inclined to switch to using a WeakMap as I considered in the issues, so there's no Symbol left on objects. The documentation could be improved, and the debugging statements taken out, but otherwise I think it's probably fine for inclusion.

As it turns out, the project I was using this for shifted focus, so I'm not currently using the code at all.
