  // ALL_EDGES Determines all "directed edges" of a given set of simplices. For
  // a manifold mesh, this computes all of the half-edges
  //
  // Inputs:
  //   F  #F by simplex_size list of "faces"
  // Outputs:
  //   E  #E by simplex_size-1  list of edges
  //
  // Note: this is not the same as igl::edges because this includes every
  // directed edge including repeats (meaning interior edges on a surface will
  // show up once for each direction and non-manifold edges may appear more than
  // once for each direction).
