How does it work?

This blueprint wraps a number of children under its dom node, which are considered 'pages' to leaf through,a s in a ppt slideshow. When a message is received on one of the prev or next input terminals, the implied action takes place. The input terminal page_request_in takes a number as oparameter, which show the coresponding page.
