/****************************************************************
 * New Photo Display Widget.
 *
 * This has two 'lists'.
 * Top list shows Albums.
 * Lower list is photos from the selected Album.
 * 
 * Notes:
 *   Each Item will be an AlbumItem, which contains a thumbnail & random details.
 *   We will limit Items to < 100. With a 'Filter to see more message.
 * 
 *   Thumbnails will come from Service.
 *   Option to Share albums / pictures onward (if permissions allow).
 *   Option to Download the albums to a specified directory. (is this required if sharing an album?)
 *
 *   Will introduce a FullScreen SlideShow later... first get basics happening.
