 In some cases it would be useful if the user can define if the input object
 should be consumed or not. For example, a validation chain like cross
 validation should estimate the performance but should also be able to return
 the example set which is then used to learn the overall model. Operators can
 change the default behavior for input consumation and a parameter will be
 automatically defined and queried. The default behavior is defined in the
 method <A HREF="../../../com/rapidminer/operator/Operator.html#getInputDescription(java.lang.Class)"><CODE>getInputDescription(Class cls)</CODE></A> and should be overriden in
 these cases. Please note that input objects with a changed input description
 must not be defined in <A HREF="../../../com/rapidminer/operator/Operator.html#getOutputClasses()"><CODE>getOutputClasses()</CODE></A> and must not be returned
 at the end of apply. Both is automatically done with respect to the value of
 the automatically created parameter. Please refer to the Javadoc comments of
 this method for further explanations.
