 // Defines a wrapper around the C libgps API (gps.h). Similar to the libgpsmm.h
 // API provided by that package, but adds:
 // - shared object dynamic loading
 // - support for (and abstraction from) different libgps.so versions
 // - configurable for testing
 // - more convenient error handling.
