Author(s):hdaniels
Created:Oct 2010
Notes:This currently handles Area updates also. New areas are created when the extent
is created, so it happens at the same time, but some code, in particular
refresh after save should use the AreaDataSource if we want to support
PUT (extents) and POST new areas, since we need the URLs that we currently add
there on read.
