// utiltkm.cc --
// some simple useful utilities 
// uran --- generates U(0,1) r.v.
// gran -- generators N(0,1) r.v.s, or pairs of them
// sort2lfd -- sort a double array, and a corresponding integer (index) array
// sort1lf -- sort a double array
// sort2fd -- sort a float array, and a corresponding integer (index) array
// sort1lf -- sort a float array

// All sorts are into increasing order
