This pull request tries to read the vertex normals from the file. If they are not present, they are calculated from the already available triangle mesh.
Note: This method will fail if the mesh is not compact, i.e. if there are vertices which are not part of a triangle. However, this would need to be addressed in the vertex normal calculation and not the reader.
