#946: hashCode functions not usable by STL containers

Component:  Default      |    Version:  master
 Severity:  Unassigned   |   Keywords:
-------------------------+--------------------------
 The `Geometry`, `Coordinate`, and `Envelope` classes provide `hashCode`
 methods ported from Java. It would be more useful to provide hashers in
 the form expected by standard library containers such as `unordered_map`
 and `unordered_set`.
