A wrapper for a typical header-body-footer layout that exposes header and footer, and delegates all methods from HasComponents to the body. In other words, it allows using predefined layouts. This component is Iterable over the Components contained in the body. Similarly, getComponents() ()} returns Components things put in the body.
