+ Support for Keyhole "kml" format.
+
+ STATUS: 03/15/2005 - This file is kind of sketchy and was based
+ on examining sample KML data files found on the net. I do now
+ have the full formal spec from Keyhole, but have not revisited
+ this file with that information yet. I'm checking it in becuase
+ there have been a couple of requests for KML support. RJL
