We want Google Auth for our app with app-framework.
We need to override a component <login-popup>
which is used in app/app.js
To override we need to create a component -> https://github.com/scriptPilot/app-framework/blob/master/docs/extend-vue-root-object.md#own-components
First, create "app/components/loginPopup.vue"
Second, register the component in the "app/vue.js" file
Third, add a route "login", there is a hardcoded route pushed in the source code of app-framework
Fourth, populate the "app/pages/login.vue" page with the content. In this case the Google Button and modify the login of user/password with the google provider
