Subject: Hey! This is a much better structure for the Json class.

This new setup is one class for everything, the values are kept in a union, and
the instance knows what type it is.  The tree of objects is a tree of
instantiations of the same class.  It's much simpler, it's much easier to write,
and maybe even easier to use.
