This widget is intended to be used in the
bodyparameter of the
PuePaqeor SoloPuePage widgets. It provides some extra functionality as opposed to just putting your own widget in the
bodysection of the PuePage (which is completely possible if you prefer). You can easily turn the body into a listview, and fade the top and bottom of the body out. It also has
guttersso that the header, body and footer can all have the same horizontal padding.
