how to fix javadoc comment in Tagger annotator

[Marshall Schor]

The class IModeResource in Tagger has this:

public interface IModelResource {
 
  /**
   * Obtain an input stream for this resource.
   * @return
   */
  ModelGeneration getModel();

ModelGeneration is not an input stream.  What should the Javadoc say?
