 // A device data provider provides data from the device that is used by a
 // NetworkLocationProvider to obtain a position fix. This data may be either
 // cell radio data or wifi data. For a given type of data, we use a singleton
 // instance of the device data provider, which is used by multiple
 // NetworkLocationProvider objects.
 //
 // This file providers DeviceDataProvider, which provides static methods to
 // access the singleton instance. The singleton instance uses a private
 // implementation to abstract across platforms and also to allow mock providers
 // to be used for testing.
 //
 // This file also provides DeviceDataProviderImplBase, a base class which
 // provides commom functionality for the private implementations.
 //
 // This file also declares the data structures used to represent cell radio data
 // and wifi data.
