+ * The CoreLocationObjects class contains the CoreLocation objects

+ * as well.
+ *
+ * The solution then is to forward-declare CoreLocationObjects here and
+ * hold a pointer to it in CoreLocationLocationProvider, and only actually
+ * define it in CoreLocationLocationProvider.mm, thus making it safe
+ * for Geolocation.cpp, which is C++-only, to include this header.
