-// 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.
