/** @name Gmsh High-Order Vertex Mappings
 
    These functions generate the mappings needed to translate the order of
    Gmsh's high-order vertices into MFEM's L2 degree of freedom ordering. The
    mapping is defined so that MFEM_DoF[i] = Gmsh_Vert[map[i]]. The @a map
    array must already be allocated with the proper number of entries for the
    element type at the given element @a order.
