Jackson Map Exception on checkinposts

Some checkins do not provide a complete location mapping, only a String telling the location.

I suggest adding a location deserializer like this:

@Override
public Location deserialize(JsonParser jp, DeserializationContext ctxt) throws IOException, JsonProcessingException {
try

{ Location node = jp.readValueAs(Location.class); return node; }

catch (Exception e)

{ Location location = new Location(jp.getText()); return null; }

}
