> GeoPointField uses morton encoding to efficiently pack lat/lon values into a
> single long. GeoHashing effectively does the same thing but uses base 32
> encoding to represent this long value as a "human readable" string. Many
> user applications already use the string representation of the hash. This
> issue simply adds the base32 string representation of the already computed
> morton code.
