/*
* The CoreLocationObjects class contains the CoreLocation objects
* we'll need.
*
* Declaring them directly in CoreLocationLocationProvider
* would require Objective-C++ syntax, which would contaminate all
* files that include this header and require them to be Objective-C++
* 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.
