Commit simplified Feature class. Features in the main OpenLayers parlance will not be the behemoth that they were in past versions, doing data parsing and everything on their own. Instead, a feature will be a minimal container for point-based data, to which other methods can be added: Feature.WFS might parse data out of XML, while Feature.Text might parse it out of CSV.
