Each HTML Widget has all of its details stored in a WidgetInfo object; Multiple Widgets can be attached to the same WidgetInfo, simplifying the usage. All the library user needs to worry about is the Widget object itself; the WidgetInfo will be managed behind the scenes.
WidgetInfo contains the basic information for all Widgets Widget is a generic base class, with a shared pointer to WidgetInfo WidgetFacet is a template that allows Set* methods to return derived return-type.

Library users should not need to access Widgets directly, only specific derived types.
