Does TIFY have an event for when the user changes pages?

[germyparker]

If a user has loaded a multiple-page manifest, and then goes to the next page, I'd love to have my "host" page respond to the page change, like, change my page's title (&c). Is that possible?

(I realize I can have external-to-Tify "prev/next" buttons and use the setPage API to change what TIFY is displaying, but that means that my external-to-tify UI has to include elements you kind folks have already written, and it feels like keeping people within The Tify Experience™ would feel more natural.)
