// A wifi data provider provides wifi data from the device that is used by a
// NetworkLocationProvider to obtain a position fix. We use a singleton
// instance of the wifi data provider manager, which is used by multiple
// NetworkLocationProvider objects.
//
// This file provides WifiDataProviderHandle, which provides static methods to
// access the singleton instance. The singleton instance uses a private
// implementation of WifiDataProvider to abstract across platforms and also to
// allow mock providers to be used for testing.
