Still plenty of missing features, and missing implementations in the
generated code. Also missing some functionality and flags for generating
references and/or well-known references (ex: XML, RDF values).
- Fixed the way indexing nodes were being applied
- Implemented property types in ontologies
- Improved class types in ontologies
- Lots of other stuff
Also adds some placeholders for the schema ontology.
Eliminated some dead code in the RDF manager thing.
Next step is to get mainEntity parsing to ignore the rest of the values,
which should be easier to do, maybe.
