  // Creates a quad mesh from a triangular mesh and a set of two directions
  // per face, using the algorithm described in the paper
  // "Mixed-Integer Quadrangulation" by D. Bommes, H. Zimmer, L. Kobbelt
  // ACM SIGGRAPH 2009, Article No. 77 (http://dl.acm.org/citation.cfm?id=1531383)
  
  // Inputs:
  //   Vin        #V by 3 eigen Matrix of mesh vertex 3D positions
  //   F          #F by 4 eigen Matrix of face (quad) indices
  //   maxIter    maximum numbers of iterations
  //   threshold  minimum allowed threshold for non-planarity
  // Output:
  //   Vout       #V by 3 eigen Matrix of planar mesh vertex 3D positions
  //
  
  
  // TODO: this returns singularity index modulo 4. It may need to be modified to cover indices
