-- Integrated the doc in the header files -- Split and moved files to have a proper internal structure and to distinguish between hosts, stencils and methods at the filename level. -- Removed all instances of Polyhedron to have PolygonMesh instead -- Cleaned off useless functions (Polyhedron_decorator remnants) -- Improved general documentation -- Minor performance improvements
