//
// The geom library defines namespaces containing classes and other
// constructs related to the geometry of spaces in various dimensions.
// This file defines:
//
// o Namespace: Geometry
//
//    Mostly constants like pi and degrees-to-radians factors, etc.
//    Meant to be of common utility to the other two spaces.
