BKB Structure Learning - Statistical Structure Learning

[GregHydeDartmouth]

Explore and implement initial algorithms for constraint-based structure learning for BKBs from our digested data services. Utilizes GDC and Reactome data services from Milestones 2 and 3.

If Reactome is not ready by the time we implement structure learning, we can simply run structure learning on the GDC data, until the pathway data is ready.

See https://github.com/di2ag/Connections-Hypothesis-Provider-Roadmap/milestone/7 for other open issues.
