 // This file defines the interface class AutocompleteEditView.  Each toolkit
 // will implement the edit view differently, so that code is inherently
 // platform specific.  However, the AutocompleteEditModel 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.
