BSPKNTINS:  Insert knots into a B-Spline

 Calling Sequence:
 
   [ic,ik] = bspkntins(d,c,k,u)

  INPUT:
 
    d - spline degree             integer
    c - control points            double  matrix(mc,nc)      
    k - knot sequence             double  vector(nk) 
    u - new knots                 double  vector(nu)               
 
  OUTPUT:
 
    ic - new control points double  matrix(mc,nc+nu) 
    ik - new knot sequence  double  vector(nk+nu)
