NUMBASISFUN:  List non-zero Basis functions for B-Spline in a given knot-span

 Calling Sequence:
 
   N = numbasisfun(i,u,p,U)
   
    INPUT:
   
      i - knot span  ( from FindSpan() )
      u - parametric point
      p - spline degree
      U - knot sequence
   
    OUTPUT:
   
      N - Basis functions (numel(u)x(p+1))
