This app is derived Ohanhi's Shared State Demo. In this example, when the user signs in sign in, his successful sign-in informatiom, e.g. a sesssion token, is stored the parent, shared state, and so is resistant to tamperign.

The app's functionality is deliberately restricted, so that it can, if desired, serve as a templaste for others.

Please consult Ohahnhi's README to understand the logic behind the shared state architecture. The main point of Ohanhi's setup is to use an augmented update function with the type signature:

update : SharedState -> Msg -> Model -> ( Model, Cmd Msg, SharedStateUpdate )

This function can be used in a child page, and the SharedStateUpdate constructor can be used to update the share state, "the parent," from the child.

For now: elm make src/Main.elm --output=Main.js. Then start elm reactor and click on index.html

NOTE When running npm run api to generate Elm code from the schema, authentication must be disabled. For the moment, this is very clunky: switch call and call1 in LogServerWeb.Context of the server.
