ONMjs.Address could still use a little cleanup...

... There's now an ONMjs.Address.implementation subclass to be used to hide detail from the top-level object's namespace. I've assimilated the ONMjs.Address factory functionality into ONMjs.Address. There are quite a few other parts of ONMjs.Address that should be moved into implementation as well.

Logically however, this is starting to get close to a reasonable API based on paths and subpath strings.
