				  e687. The Quintessential Accessible Object
				
				You should try to subclass from JComponent or one of its descendants
				since that will automatically make your object accessible. If that is
				not possible, your object should implement Accessible.
				
				
				    import javax.accessibility.*;
				    
				    public class BasicAccessible implements Accessible {
				        public AccessibleContext getAccessibleContext() {
				            return new AccessibleContext() {
				                // Implement all the abstract methods in this abstract class.
				            };
				        }
				    }
