Hello all
Following on the move of QuadTree related classes to the
"org.apache.index.tree" package, I realized that GeoHashUtils could also
be seen as a kind of index. Would it be okay to do the following?
* Move it to the "org.apache.sis.index" package.
* Move it from "sis-referencing" to "sis-storage" module, together
with QuadTree.
* Rename it as "GeoHashCoder" by analogy with the "geocoding" process [1].
* Make the methods non-static, for allowing configuration (precision,
32 vs 36 bits variants)
Other ideas are welcome if "...sis.index" seems weird for that class.
