Alternatively: I think that *public* methods in the controller can be
accessed from within the view by using the 'controller' accessor. e.g.

<%= controller.render_to_string %>

But this is probably not a good idea if render_to_string is a method which
you don't want to make available to the outside world (in which case you
should mark it 'private')
