 * Carousels, like tabs, are a great way to allow the user to swipe through
 * multiple full-screen pages. A Carousel shows only one of its pages at a time
 * but allows you to swipe through with your finger. <br>
 * <br>
 * Carousels can be oriented either horizontally or vertically and are easy to
 * configure - they just work like any other Container.
