* Gets the <code>Action</code> specified by the mapping type from a PicoContainer. The action

* instantiated via a special PicoContainer that just contains actions. If this container already
* exists in the request attribute, this method will use it. If no such container exists, this
* method will create a new Pico container and place it in the request. The parent container will
* either be the request container, or if that container can not be found the session container,
* or if that container can not be found, the application container. If no parent container can be
* found, a <code>PicoInitializationException</code> will be thrown. The action path specified in
* the mapping is used as the component key for the action.
*
* @param request the Http servlet request.
* @param mapping the Struts mapping object, whose type property tells us what Action class is
* required.
* @param servlet the Struts <code>ActionServlet</code>.
* @return the <code>Action</code> instance.
* @throws PicoIntrospectionException if the mapping type does not specify a valid action.
* @throws PicoInitializationException if no request, session, or application scoped Pico
