An overly simple Model-Glue app

So there is good documentation on Model-glue framework. I followed along with their “Pig Latin Translator” but decided I need something more realistic. Who uses a translator that translates to “Pig Latin”? So here is a more realistic Login –> Validate Login –> show view on correct login || show error and login screen on bad login info type application in Model Glue.
If you understand this and follow, you’d have known the most of model glue in its basic form.
