DISCO: import data for RGD

DISCO id: nif-0000-00134

RGD states it has an interop file, but it's blank. So, we need to pull in data!

Their data files are nicely mapped to ontologies, here:
ftp://rgd.mcw.edu/pub/data_release/annotated_rgd_objects_by_ontology/with_terms/

Take just the "rattus" data. (We actually need to investigate further, here, whether or not the "human" and "mouse" annotations in RGD are things they curated, and therefore found nowhere else, or if they are slurped from outside resources....I'm assuming the latter.)

with a nice readme about the format.

Note that the ontologies used for diseases come from CTD

• rdo: "RGD Disease Ontology" imported from the Comparative Toxicogenomics Database (CTD) (originally referred to as "ctd", replaces 'do' ontology).
• nbo: Neuro Behavioral Ontology (replaces 'bo' ontology)
