Alright, let me see if I've got this straight. The link(...) method
returns a PageLink object that's used to create the href attribute to
an anchor tag. And I have to not only create the link(...) method,
but I also have to call that method in each class that's going to link
to that page. Then I need to put that hook into the HTML file. Does
that sound right? I hope I'm wrong, because that seems like a lot of
work for a simple page link.
