  // Computes principal matchings of the vectors of a frame field across face edges,
  // and generates a combed frame field defined on the mesh faces. This makes use of a
  // combed cross field generated by combing the field created by the bisectors of the
  // frame field.

  // Inputs:
  //   V            #V by 3 eigen Matrix of mesh vertex 3D positions
  //   F            #F by 4 eigen Matrix of face (quad) indices
  //   PD1          #F by 3 eigen Matrix of the first per face cross field vector
  //   PD2          #F by 3 eigen Matrix of the second per face cross field vector
  //   BIS1_combed  #F by 3 eigen Matrix of the first combed bisector field vector
  //   BIS2_combed  #F by 3 eigen Matrix of the second combed bisector field vector
  // Output:
  //   PD1_combed  #F by 3 eigen Matrix of the first combed cross field vector
  //   PD2_combed  #F by 3 eigen Matrix of the second combed cross field vector
