It is sillier then that - the docs are for trunk; ie GeoTools 2.7 - where we
have just introduced SimpleFeatureCollection rather then forcing people to type
FeatureCollection<SimpleFeatureType,SimpleFeature> again and again and again...
We are not really sure how we should publish older docs; perhaps as a download
next to the release?
