UAF14 — UAFElement.conformsTo and ProtocolImplementation.implements alignment and reification with fUML

UAF::ProtocolImplementation is really a subset of all UAFElement.conformsTo Standards. Aka if a UAF::ProtocolImplementation implements a UAF::Protocol it should also count as conformingTo it. Recommend making the implements tag a subsetted property of the conformsTo tag. Also, to allow Standards to actually enforce parametric constraints or execute behavioral simulations as part of UAF models, recommend creating a <<ConformsTo>> property stereotype that has <<Standard>> as a target and <<UAFElement>> as a Source (or maybe just limit to PropertySet), and/or add a derived Tag to UAFElement that derives a subset of conformsTo relationships from classifier.properties that have <<Standard>> or stereotypes derived from <<Standard>> as their type.
