The current page element.
The series links element.
This template is called by mal2html.links.series to output the pages after the starting page in the series. This template finds the next page for the page $node. It outputs a link to that page, then calls itself recursively on that page.
If $node is part of a series-type stack, this template uses the next page in the stack. Otherwise, it looks for a next-type link in $node.
