      Description

      I'm opening this for discussion, because I'm not yet sure how to do
      this integration, because of my ignorance about spatial in general and
      spatial3d in particular

      Our BKD tree impl is very fast at doing lat/lon shape intersection
      (bbox, polygon, soon distance: LUCENE-6698) against previously indexed
      points.

      I think to integrate with spatial3d, we would first need to record
      lat/lon/z into doc values. Somewhere I saw discussion about how we
      could stuff all 3 into a single long value with acceptable precision
      loss? Or, we could use BinaryDocValues? We need all 3 dims available
      to do the fast per-hit query time filtering.

      But, second: what do we index into the BKD tree? Can we "just" index
      earth surface lat/lon, and then at query time is spatial3d able to
      give me an enclosing "surface lat/lon" bbox for a 3d shape? Or
      ... must we index all 3 dimensions into the BKD tree (seems like this
      could be somewhat wasteful)?
