Title: implement Cadenza::ContextObject

- in order to be invokeable, all non-array, non-hash objects bound to the context must be subclasses
- before/after callbacks are available by implementing before_method(method) and after_method(method)
- a safe method_missing for context's is available by implementing missing_context_method(method)
