  UNI-DIMENSIONAL DYADIC SPLINES
  
  A spline is /dyadic/ if its mesh {L} is a finite dyadic grid {G}.
   
  We are particularly interested in the space {S_c(P^g,G)} where {G}
  is a uni-dimensional dyadic grid; namely, the /dyadic polynomial
  splines on {G} with continuity {c} and degree {g}/. */
