<P> This operator can be used for manual feature selection, which means that the 
  user specifies all features to be selected. This is done by providing all and 
  only the features that are to be selected in <I>TheOutputConcept</I>. The operator 
  then simply copies those features from <I>TheInputConcept</I> to <I>TheOutputConcept</I> 
  which are present in <I>TheOutputConcept</I>. It can be used to get rid of features 
  that are not needed in later parts of the operator chain. All features in <I>TheOutputConcept</I> 
  must have a corresponding feature (with the same name) in <I>TheInputConcept</I>.
