Consolodate the code for registering a schema & a specialization.

Consolodate the code for registering a schema & a specialization. The "parse_schema" fn and "parse_specialization" fn are nearly identical. This is because the JSON Schema used to define an ontology for the Q is the same for schemas and specializations. Surely, therefore, I can consolidate those 2 functions to avoid code duplication.

Note, that once this is done, I can no longer decide whether or not to render a component hierarchy based on whether the ontology is a specialization or a schema but on whether it explicitly has any hierarchical properties.
