You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: cfg_struct2cfg.m
    path of file: ./repos/bspm/thirdparty/spm8/matlabbatch
    
    the code of the file until where you have to start completion: function cc = cfg_struct2cfg(co, indent)

% Import a config structure into a matlabbatch class tree. Input structures
% are those generated from the configuration editor, cfg2struct methods or
% spm_jobman config structures.
%

    
function cc = cfg_struct2cfg(co, indent)

% Import a config structure into a matlabbatch class tree. Input structures
% are those generated from the configuration editor, cfg2struct methods or
% spm_jobman config structures.
%
% The layout of the configuration tree and the types of configuration items
% have been kept compatible to a configuration system and job manager
% implementation in SPM5 (Statistical Parametric Mapping, Copyright (C)
% 2005 Wellcome Department of Imaging Neuroscience). This code has been
% completely rewritten based on an object oriented model of the
% configuration tree.
%
% This code is part of a batch job configuration system for MATLAB. See 
%      help matlabbatch
% for a general overview.
