  immediately before returning an Estimate object (in functions Estimator(), 
  MCEstimator(), MDEstimator(), MLEstimator()); this allows to return an
  object of S4 class specific to the resp. parametric family (by means of
  S4 method dispatch); this is used in pkg 'RobExtremes' to produce, e.g., 
  objects of class "GEVMCEstimate", i.e. which inherit from both "MCEstimate" 
  and "GEVEstimate", so that a diag-method for "GEVEstimate" becomes available 
  for this class.
