The layout dictionary specifies the layout of the widgets on page.  The type is used by a dashboard layout factory to produce a specialised dashboard layout widget .  Initially, there will be only one dashboard layout widget known as singleColumn.  It arranges the widgets vertically according to widget entries within an array list.  Widgets are identified by a identifier.  The widget identifier will be private and will neither be understood by  the end user nor the server.
