/**
* @class vtkBezierWedge
* @brief A 3D cell that represents an arbitrary order Bezier wedge
*
* vtkBezierWedge is a concrete implementation of vtkCell to represent a
* 3D wedge using Bezier shape functions of user specified order.
* A wedge consists of two triangular and three quadrilateral faces.
* The first six points of the wedge (0-5) are the "corner" points
* where the first three points are the base of the wedge. This wedge
* point ordering is opposite the vtkWedge ordering though in that
* the base of the wedge defined by the first three points (0,1,2) form
* a triangle whose normal points inward (toward the triangular face (3,4,5)).
* While this is opposite the vtkWedge convention it is consistent with
* every other cell type in VTK. The first 2 parametric coordinates of the
* Bezier wedge or for the triangular base and vary between 0 and 1. The
* third parametric coordinate is between the two triangular faces and goes
* from 0 to 1 as well.
