o) we have had some problems, but they are solved now
     ---> tests/wgt-himed.R etc	  {MM, Dec.2005}

2) I think its wrong in principle to only work with *integer* weights
      for 'whimed'.
      Further note, that *because* of the integer weights, we need type
      'long long' {because otherwise integer overflow kills everything}.

   Using C Macro, we now have both, integer and double weights;
   and I have tests of consistency in ./tests/
   --> using wgt.himedian() as an R function {MM, Dec.2005}

   Note however that a more general function (weighted quantiles) might be
   of interest, see file ./TODO

3) Data Sets --- Valentin Todorov has several of Rousseeuw's
	     in his "rrov" package

   --> got them, and dropped all *.x and *.y data sets
       -- as part of the loaded data -- but kept a definition
        <foo>.x <- as.matrix(.....)
      in the examples section.	 {MM & VT,  Dec.2005/Jan.2006}

4) covMcd( * ):  replace 'print.it'  by  'trace'  which is more appropriate
   	         and common in S

5) renamed  tolellipse() to tolEllipsePlot()
   all these plotting functions may *NOT* set  par(mfrow = c(1,1)) !

6) considerable simplification in the  correction factor computations
