Title: Predicate file rename

Michael, per your request prior, I'm refactoring the predicates.yml file to associations.yml.

Stephen, per your request, I introduced the ability to detect and raise exception when we attempt to construct duplicate association types. This change goes hand in hand with changes to pyon and coi-services. See pull requests for those repos (coming soon).
