/**
 * @class   vtkYoungsMaterialInterface
 * @brief   reconstructs material interfaces
 *
 *
 * Reconstructs material interfaces from a mesh containing mixed cells (where several materials are
 * mixed) this implementation is based on the youngs algorithm, generalized to arbitrary cell types
 * and works on both 2D and 3D meshes. the main advantage of the youngs algorithm is it guarantees
 * the material volume correctness. for 2D meshes, the AxisSymetric flag allows to switch between a
 * pure 2D (planar) algorithm and an axis symmetric 2D algorithm handling volumes of revolution.
 *
 * @par Thanks:
 * This file is part of the generalized Youngs material interface reconstruction algorithm
 * contributed by <br> CEA/DIF - Commissariat a l'Energie Atomique, Centre DAM Ile-De-France <br>
 * BP12, F-91297 Arpajon, France. <br>
 * Implementation by Thierry Carrard (thierry.carrard@cea.fr)
