> {{GeoPointField}} is a lightweight dependency-free postings based geo field currently
in sandbox. It has evolved into a very fast lightweight geo option that heavily leverages
the optimized performance of the postings structure. It was originally intended to graduate
to core but this does not seem appropriate given the variety of "built on postings" term encoding
options (e.g., see LUCENE-6930).  
> Additionally, the {{Geo*Utils}} classes are dependency free lightweight relational approximation
utilities used by both {{GeoPointField}} and the BKD based {{LatLonField}} and can also be
applied to benefit the lucene-spatial module.
> These classes have been evolving and baking for some time and are at a maturity level
qualifying for promotion from sandbox. This will allow support for experimental encoding methods
with (minimal) backwards compatibility - something sandbox does not allow.
> Since GeoPoint classes are dependency free, all GeoPointField and support and utility
classes currently in sandbox would be promoted to the spatial3d package. (possibly a separate
issue to rename spatial3d to spatialcore or spatiallite?) Such that for basic lightweight
Geo support one would only need a handful of lucene jars. By simply adding the lucene-spatial
module and its dependency jars users can obtain more advanced geospatial support (heatmap
facets, full shape relations, etc).
