/**
 * An Association Class is represented by 3 separate Figs:
 * <nl>
 * <li>FigAssociationClass is the association edge drawn between two
 * classifiers this displays that association properties of the association
 * class.</li>
 * <li>FigClassAssociationClass is the classifier box that displays the class
 * properties of the association class.</li>
 * </li>
 * FigEdgeAssociationClass is the dashed line that joins these two.</li>
 * </nl>
 *
 * Whenever the user attempts to remove or delete one of these parts then all
 * parts must go. Delete would be handled because the model element is deleted
 * and all parts are listening for such an event and will remove themselves.
 * However if the user attempts to just remove from diagram one of these parts
 * then there is no such event. Hence the removeFromDiagram method is overridden
 * to delegate removal from a single removeFromDiagram method on
 * FigAssociationClass.
