It could be more convenient to use annotations to indicate whether a pagelet is a barrier or a pipe

There is even no need to use an annotation, since pagelet type can be decided when the base view gets parsed('pb-pipe' or 'pb-barrier')

Now in plumber-1.2.0-SNAPSHOT , a pagelet (barrier or pipe) no longer need to implement the specific interface. Just extending the abstract class of PlumberPagelet, plumber will get the pagelet type by parsing the view source('pb-pipe' or 'pb-barrier').

Thanks for the suggestion. And the adjustment of the code is here.
