  //Export geometry and colors-by-vertex

  // Templates:
  //   Scalar  type for positions and vectors (will be read as double and cast
  //     to Scalar)
  //   Index  type for indices (will be read as int and cast to Index)
  // Inputs:
  //  str  path to .off output file
  //   V  #V by 3 mesh vertex positions
  //   F  #F by 3 mesh indices into V
  //   C  double matrix of rgb values per vertex #V by 3
  // Outputs:
  // Returns true on success, false on errors
