GeoLocationProbe class

Collects geolocation information from the underlying OS's location API. Is a StreamProbe that generates a LocationDatum every time location is changed. Takes a LocationMeasure as configuration.

Note that in order for location tracking to work with this probe, the phone must be online on the internet, since Google APIs are used.
