      Description

      Add ST_Covers, ST_CoveredBy, ST_Relate spatial functions.

      There are subtle differences between ST_Contains and ST_Covers; ST_Covers is usually what you want, and is easier to compute.

      Extend the Hilbert spatial index (added in CALCITE-1861) to handle ST_Covers, ST_CoveredBy, ST_ContainsPropertly as it does ST_DWithin and ST_Contains.

      It might make sense to also implement ST_ExteriorRing so that we can implement the PostGIS example.
