// .NAME vtkQuadraticTetra - cell represents a parabolic, 10-node isoparametric tetrahedron
// .SECTION Description
// vtkQuadraticTetra is a concrete implementation of vtkNonLinearCell to
// represent a three-dimensional, 10-node, isoparametric parabolic
// tetrahedron. The interpolation is the standard finite element, quadratic
// isoparametric shape function. The cell includes a mid-edge node on each of
// the size edges of the tetrahedron. The ordering of the ten points defining
// the cell is point ids (0-3,4-9) where ids 0-3 are the four tetra
// vertices; and point ids 4-9 are the midedge nodes between (0,1), (1,2),
// (2,0), (0,3), (1,3), and (2,3).
