    Add Lagrange polynomial higher-order cells to VTK. · cc5101a8

    This commit adds support for Lagrange cells of the following shape:
    curve, triangle, quadrilateral, tetrahedron, hexahedron, and wedge.
    The new cell types may have arbitrary order, up to a compile-time maximum of 10.
    The maximum may be changed easily.
    The order is inferred from the number of points defining the cell
    and is assumed to be the same along each coordinate axis.
    Visualization operations that cells must provide (contouring, clipping, cutting)
    are implemented by approximating each higher-order cell as a collection of
    multi-linear "primitive" cells of the same shape.
    Note that the wedge element, when asked for boundary faces, returns faces
    with outward-pointing normals. This is not the same convention as vtkWedge
    but is the same as other VTK cell shapes.
    See the vtkCellTypeSource class in vtkFiltersSources for an example of how
    cell connectivity is specified. In general, the shape corner points are
    specified first, matching the linear cell coun...
