3D Barycentric Coordinates for Convex Polyhedra with Triangular Faces

For this project, I would like to implement 3D Barycentric Coordinates for Convex Polyhedra with Triangular Faces, which is one of the ideas for this year GSoC. The goal of this project is to extend the CGAL package 2D Generalized Barycentric Coordinates to 3D space, to achieve this, it is necessary to implement several coordinate types, which include coordinates for tetrahedra, 3D Wachspress, mean value, and discrete harmonic coordinates.
