restimate,CovControlMest-method

Each concrete control class, like <code>CovControlMest</code>, <code>CovControlOgk</code>,
 etc., should implement an <code>restimate</code> method which will call the correponding
 (constructor)-function and will return the obtained S4 class, derived from
 <code>CovRobust</code>.
