+Retrieve the last position of a particular user. In addition to the values obtained in the [`location` publish](http://owntracks.org/booklet/tech/json/) from the OwnTracks device, there are a few which we return as convenience:
+
+* `username` contains the name of the user obtained from the publish topic
+* `device` contains the user's device name as obtained from the publish topic
+* `topic` is the full topic to which the payload was published
+* `ghash` is the geohash string which corresponds to `lat` and `lon`
+* `isotst` is the ISO timestamp of the publish time (`tst`)
+* `disptst` is the same but designed for displaying
+* `cc` is the country code of the location point if available in the cache (see below)
+* `addr` is the address of the location point if available in the cache
