This updates the biomedical schema to make a new parent class "Association" (subClassOf: schema:Thing), of which all association type nodes are a subclass. At this time this includes the classes: ChemicalCompoundAssociation, DiseaseAssociation, and GeneticAssociation. All node types in BMDC that are association nodes are subclasses of one or more of these three association subtypes. The superclass ensures that all of these Association nodes are identifiable.
