> Real-world polygons (e.g. from ESRI) have holes in them.  We need polygon support in
geo3D that works in the same way.
> The proposal would be to change the GeoConvexPolygon constructor to include a number
of GeoPolygon inputs, each of which would specify a hole.  Then, the GeoPolygonFactory.makeGeoPolygon()
method would also need to accept a similar list of GeoPolygon hole descriptions.
> This change is likely to be fairly complex because of the already tricky algorithm used
to create convex polygons from non-convex ones, implemented in GeoPolygonFactory.
