Examples of org.geotools.data.crs.ReprojectFeatureResults

org.geotools.data.crs.ReprojectFeatureResults
ReprojectFeatureReader provides a reprojection for FeatureTypes.
ReprojectFeatureResults is a wrapper used to reproject GeometryAttributes to a user supplied CoordinateReferenceSystem from the original CoordinateReferenceSystem supplied by the original FeatureResults.

Example Use:
```
 ReprojectFeatureResults results = new ReprojectFeatureResults( originalResults, reprojectCS ); CoordinateReferenceSystem originalCS = originalResults.getFeatureType().getDefaultGeometry().getCoordinateSystem(); CoordinateReferenceSystem newCS = results.getFeatureType().getDefaultGeometry().getCoordinateSystem(); assertEquals( reprojectCS, newCS ); 
```
