Creating a GeoRSS Service is simple:

  >>> import FeatureServer.Service.GeoRSS as G
  >>> g = G.GeoRSS({})

It is then possible to use coordinates_to_geom to convert from
a string to a geometry.
  
  >>> g.coordinates_to_geom("1 2", "Point")
  {'type': 'Point', 'coordinates': [[2.0, 1.0]]}
  
  >>> g.coordinates_to_geom("1,2", "Point")
  {'type': 'Point', 'coordinates': [[2.0, 1.0]]}
  
  >>> g.coordinates_to_geom("1,2 3,4", "Line")
  {'type': 'Line', 'coordinates': [[2.0, 1.0], [4.0, 3.0]]}
  
  >>> g.coordinates_to_geom("1 2 3 4", "Box")
  {'type': 'Polygon', 'coordinates': [[[2.0, 1.0], [4.0, 1.0], [4.0, 3.0], [2.0, 3.0], [2.0, 1.0]]]}

Additionally, it is possible to use extract_entry_geometry to pull
a geometry out of an entry. This example is a polygon from a Google
Maps "MyMaps" feed. Note that the GML is lacking a georss:where 
element, so it is invalid, but FeatureServer parses it, attempting to
be 'lenient in what it accepts'.
