This is a simple example of using the library list zipper implementation
to implement a basic slideshow functionality allowing remote commands to
navigate to the next, previous, first, and last slide in a sequence of
slides. The slides are represented using a predicate with two arguments,
the index and the slide contents. The main predicate, `show/2` takes a
sequence of slides and the name of the predicate, which is used as a
closure for displaying the slides.
