/**
* @class vtkHexahedron
* @brief a cell that represents a linear 3D hexahedron
*
* vtkHexahedron is a concrete implementation of vtkCell to represent a
* linear, 3D rectangular hexahedron (e.g., "brick" topology). vtkHexahedron
* uses the standard isoparametric shape functions for a linear
* hexahedron. The hexahedron is defined by the eight points (0-7) where
* (0,1,2,3) is the base of the hexahedron which, using the right hand rule,
* forms a quadrilaterial whose normal points in the direction of the
* opposite face (4,5,6,7).
