// This file defines the interface class AutocompletePopupView.  Each toolkit
// will implement the popup view differently, so that code is inheriently
// platform specific.  However, the AutocompletePopupModel needs to do some
// communication with the view.  Since the model is shared between platforms,
// we need to define an interface that all view implementations will share.
