In general in Cairngorm you maintain state in the model and have the
view listen to changes to the state and react accordingly. So add a
variable to your model locator loggedIn:Boolean. Then have your login
screen listen to changes in the variable either via a ChangeWatcher
or Binding, and clear the controls when it goes false.
