The app. is going to use a date based versioning system going forward. The format is yyyy.mm.dd.build. The build number is the build for that day and not a 'total' build (I.E. the total amount of time the app. has been built).
Note: Visual Studio does not like it when you use '01' (I.E. January). It does not compile because it does not match any reg-ex patterns specified by the UWP. Instead, you must use '1' to represent January and '11' for November. This is a minor formatting concern from an end-user's perspective but a fixed position for the developer.
The logic for 'factory3' and 'gallery3' is still in place but is not bound to the view (MainPage.xml). The view xml is commented out and not removed. This should make it easier to re-add it if the need comes about.
'factory2' was not updating its timestamp when it received a new reading. It was binding to the wrong property in MainPage.xml (view model). This changes the property to the correct one.
