* Refactored code; moved mutable fields into a separate inner class.
* Added resolvedProperty to ResolveResults class.
* Set resolved document name, even if it does not resolve correctly, so we can give a better error message later.
* If the document name is explicitly set, and it does not resolve, don't try any further.
* If document name is set, use that instead of the ObjectIdentifier's owner when looking up the document object.
