Routes for fetching ontology terms should provide aspect/category

Routes for fetching ontology terms should provide aspect/category.

For example, https://api.monarchinitiative.org/api/ontology/term/GO%3A0003677 should also provide what the aspect of that GO term is.

As a side note, the response provided by /ontology/ routes are different from other routes. Looks like its not marshaling the response.
