Devise a strategy for an interactive sepio ontology query engine

[toneillbroad]

The team discussed using the genegraph-ui (genegraph explorer) as the place to implement this, but putting this under the genegraph project.

Given the generic nature of the genegraph graphql model, where SEPIO class values are passed as arguments to queries, we need to devise a strategy for allowing our internal and external graphql users to search the SEPIO ontology easily to find necessary values.

Some of the functionality I would envision:

• limit the SEPIO ontology being queried to a specific domain (i.e gene disease validity, gene dosage)
• ability to query just classes, just properties or both
• ability to query by sepio term, or description term(s)
• ability to visualize the inheritance model of terms

@tnavatar I'm sticking this in the iceBox. I'm not sure when we will get back to this.
