// .NAME vtkPentagonalPrism - a 3D cell that represents a prism with
// pentagonal base
// .SECTION Description
// vtkPentagonalPrism is a concrete implementation of vtkCell to represent a
// linear 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).
// .SECTION Thanks
// Thanks to Philippe Guerville who developed this class.
// Thanks to Charles Pignerol (CEA-DAM, France) who ported this class under
// VTK 4. <br>
// Thanks to Jean Favre (CSCS, Switzerland) who contributed to integrate this
// class in VTK. <br>
// Please address all comments to Jean Favre (jfavre at
