This pull request provides a three-dimensional case of spherical coordinate system for geodetic CRS. This is provided for completeness after #117, but may not be merged because usage of 3D CRS in current GeoTIFF specification is permitted but not explicitly described. This is provided for discussion purpose only.
This pull request come after #117. Only the last commit should be checked for avoiding distraction.
