Cryo - pickle for JavaScript (serialize functions, object references, etc.)

I'm definitely going to put a disclaimer on the readme... "generally, if you are using this to solve a problem, you should come up with a better way to solve the problem."

However, sometimes - especially for quick and dirty stuff - this sort of freezing can be super useful. Also, it can work exactly like extended JSON, as it will store 'undefined' and 'Infinity' and will correctly dereference objects back into the same object (instead of multiple copies of the same data), etc.
