Made cmb parser and writer in discrete to handle full 3D topology.
CMB parsers and writers in discrete bridge could not handle full 3D models, meaning they can't write and read a 3D model with faces, edges and vertices. This constraint prevented the 3D discrete model being processed by meshers that require full 3D topolgy. With this commit, 3D models with edges can now be written and loaded with the cmb writers and parsers.
