  Library was created for files median.c, lms.c and lts.c.
2005-01-05 Vesa Oikonen
  Changes in comments etc not affecting compiled code.
2005-01-07 KS
  lts.c is now using function dmedian from median.c so functions and 
  definitions for calculation of median could be removed from lts.c and
  lts.h.
  Calculation of median changed so that if we have even number of observations,
  median value is average of the two middle values. Old functions chose the 
  the smaller middle value.
