Adding the ability to give flexible headers and content type

Example in the JS code is:
        bgGeo.configure(callbackFn, failureFn, {
                        url: ‘somewhere + UUID, // <-- only required
for Android; ios allows javascript callbacks for your http
                        params: {
        // HTTP POST params sent to your server when persisting
locations.
                        },
                        headers: {
                                "Content-type":
"application/x-www-form-urlencoded",
                                "auth_uuid": UUID,
                                "auth_token": TOKEN,
                        },
                        desiredAccuracy: 10,
                        stationaryRadius: 20,
                        distanceFilter: 30,
                        debug: true // <-- enable this hear sounds for
background-geolocation life-cycle.
                        });
