 // Defines the Geolocation access token store, and associated factory function.
 // An access token store is responsible for providing the API to persist
 // access tokens, one at a time, and to load them back on mass.
 // The API is a little more complex than one might wish, due to the need for
 // prefs access to happen asynchronously on the UI thread.
 // This API is provided as abstract base classes to allow mocking and testing
 // of clients, without dependency on browser process singleton objects etc.
