[stringtemplate-interest] v4 model adaptor unit tests

[Rafael Chaves]

It seems the way an adaptor passes up the opportunity to address a
property is by throwing an exception. Is that correct, or does the
exception signals a real error and aborts property resolution? It was
not clear from the test cases as both adaptors handle the exact same
properties.

If that is correct, doesn't throwing exceptions for the majority of
properties being resolved (which in the normal case would be handled
by the default ObjectModelAdaptor) create a lot of unnecessary
objects?

I handled the case of not understanding a property by returning null,
but that does not allow actually returning null as the intended value.
Could be returning some other object (a DOES_NOT_UNDERSTAND string
constant, for instance) instead.

Cheers,

Rafael
