/**
* @class vtkPyramid
* @brief a 3D cell that represents a linear pyramid
*
* vtkPyramid is a concrete implementation of vtkCell to represent a 3D
* pyramid. A pyramid consists of a rectangular base with four triangular
* faces. vtkPyramid uses the standard isoparametric shape functions for
* a linear pyramid. The pyramid is defined by the five points (0-4) where
* (0,1,2,3) is the base of the pyramid which, using the right hand rule,
* forms a quadrilaterial whose normal points in the direction of the
* pyramid apex at vertex #4.
