// FACES_FIRST Reorder vertices so that vertices in face list come before
// vertices that don't appear in the face list. This is especially useful if
// the face list contains only surface faces and you want surface vertices
// listed before internal vertices
//
// [RV,RT,RF,IM] = faces_first(V,T,F);
//
// Templates:
// MatV matrix for vertex positions, e.g. MatrixXd
// MatF matrix for face indices, e.g. MatrixXi
// VecI vector for index map, e.g. VectorXi
// Input:
// V # vertices by 3 vertex positions
// F # faces by 3 list of face indices
// Output:
// RV # vertices by 3 vertex positions, order such that if the jth vertex is
// some face in F, and the kth vertex is not then j comes before k
// RF # faces by 3 list of face indices, reindexed to use RV
// IM #V by 1 list of indices such that: RF = IM(F) and RT = IM(T)
// and RV(IM,:) = V
//
//
// Example:
// // Tet mesh in (V,T,F)
// faces_first(V,F,IM);
// T = T.unaryExpr(bind1st(mem_fun( static_cast<VectorXi::Scalar&
// (VectorXi::*)(VectorXi::Index)>(&VectorXi::operator())),
// &IM)).eval();
