WIdget to upload shapefile to Web AppBuilder

Idea created by jyh on Mar 3, 2015
    This would work the same way as adding a zipped shapefile to a web map.  I'm suggesting this because the AppBuilder has more extensive editing tools than a basic web map.  After users of the app upload their own data, they could then do things like compare their data with layers in the app, or add GPS data to use as a guide when editing.  If users can save a copy of the app, then the shapefile would remain in the copy.
