* @class vtkPentagonalPrism
* @brief a 3D cell that represents a convex prism with
* pentagonal base
*
* vtkPentagonalPrism is a concrete implementation of vtkCell to represent a
* linear convex 3D prism with pentagonal base. Such prism is defined by the
* ten points (0-9), where (0,1,2,3,4) is the base of the prism which, using
* the right hand rule, forms a pentagon whose normal points is in the direction
* of the opposite face (5,6,7,8,9).
*
* @par Thanks:
* Thanks to Philippe Guerville who developed this class.
* Thanks to Charles Pignerol (CEA-DAM, France) who ported this class under
* VTK 4.
* Thanks to Jean Favre (CSCS, Switzerland) who contributed to integrate this
* class in VTK.
* Please address all comments to Jean Favre (jfavre at cscs.ch).
*
* @par Thanks:
* The Interpolation functions and derivatives were changed in June
* 2015 by Bill Lorensen. These changes follow the formulation in:
* http://dilbert.engr.ucdavis.edu/~suku/nem/papers/polyelas.pdf
* NOTE: An additional copy of this paper is located at:
* http://www.vtk.org/Wiki/File:ApplicationOfPolygonalFiniteElementsInLinearElasticity.pdf
