/**
* A {@code LocationCallback} is used to run code after a Location has been fetched by
* {@link com.parse.ParseGeoPoint#getCurrentLocationInBackground(long, android.location.Criteria)}.
* <p/>
* The easiest way to use a {@code LocationCallback} is through an anonymous inner class. Override the
* {@code done} function to specify what the callback should do after the location has been
* fetched. The {@code done} function will be run in the UI thread, while the location check
* happens in a background thread. This ensures that the UI does not freeze while the fetch happens.
* <p/>
* For example, this sample code defines a timeout for fetching the user's current location, and
* provides a callback. Within the callback, the success and failure cases are handled differently.
* <p/>
* <pre>
* ParseGeoPoint.getCurrentLocationAsync(1000, new LocationCallback() {
* public void done(ParseGeoPoint geoPoint, ParseException e) {
* if (e == null) {
* // do something with your new ParseGeoPoint
* } else {
* // handle your error
* e.printStackTrace();
* }
* }
* });
* </pre>
