/**
 * An association end is an endpoint of an association, which connects the
 * association to a classifier. Each association end is part of one association.
 * The association ends of each association are ordered.
 *
 *
 *
 * In the metamodel, an AssociationEnd is part of an Association and specifies the
 * connection of an Association to some other Classifier. Because AssociationEnds
 * are a kind of StructuralFeature, they are owned and ordered by Association
 * instances via the ClassifierFeature association. The StructuralFeatureType
 * association is used to identify the Classifier to which the AssociationEnd is
 * attached. Each AssociationEnd has a name and defines a set of properties of the
 * connection.
 *
 *
 *
 * The multiplicity property of an association end specifies how many instances of
 * the classifier at a given end (the one bearing the multiplicity value) may be
 * associated with a single instance of the classifier at the other end. The
 * association end also states whether or not the connection may be traversed
 * towards the instance playing that role in the connection (the isNavigable
 * attribute), that is, if the instance is directly reachable via the association.
