/**
 * Concrete implementation of Visitor which simply checks traversals.
 * This can be a useful class for other Visitor implementations to extend, 
 * as it provides a default implementation in case you one is only interested
 * in one PicoVisitor type.  Example:
 *
 *<pre>
 * PicoContainer container = new DefaultPicoContainer();
 * PicoContainer child = container.makeChildContainer();
 *
 * final List allContainers = new ArrayList();
 *
 * PicoVisitor visitor = new TraversalCheckingVisitor() {
 *     public void visitContainer(PicoContainer pico) {
 *         super.visitContainer(pico);  //Calls checkTraversal for us.
 *         allContainers.add(pico);
 *     }
 * }
 * </pre>
