Add basic form-based disease-phenotype entry

[cmungall]

First pass should have 3 fields:

1. Disease
2. Phenotype
3. Publication

(To make things simpler, as a very first pass, omit 3.)

1. The value of 1 should be anything from the disease ontology (D)
2. The value of 2 should be anything from the phenotype ontology (Ph)
3. The value of 3 will at first pass be a string (first pass) (Pub)

This should map to a graph in the following way:

• generate IRI for disease instance, di
• generate IRI for phenotype instance, pi
• create 3 triples
  • di rdf:type D
  • pi rdf:type Ph
  • di RO_0002200 pi

Check with @hdietze for modeling of Pub

I think this ticket became closable when the original WebPhenote work was performed, and is perhaps superseded by #17, which is blocked on the review of two PRs (Noctua and bbop-client-barista).
