/**
* @class vtkQuadraticWedge
* @brief cell represents a parabolic, 15-node isoparametric wedge
*
* vtkQuadraticWedge is a concrete implementation of vtkNonLinearCell to
* represent a three-dimensional, 15-node isoparametric parabolic
* wedge. The interpolation is the standard finite element, quadratic
* isoparametric shape function. The cell includes a mid-edge node. The
* ordering of the fifteen points defining the cell is point ids (0-5,6-14)
* where point ids 0-5 are the six corner vertices of the wedge, defined
* analogously to the six points in vtkWedge (points (0,1,2) form the base of
* the wedge which, using the right hand rule, forms a triangle whose normal
* points away from the triangular face (3,4,5)); followed by nine midedge
* nodes (6-14). Note that these midedge nodes correspond lie on the edges
* defined by (0,1), (1,2), (2,0), (3,4), (4,5), (5,3), (0,3), (1,4), (2,5).
