New feature

In `checkCFG.m`   


 fieldsToSet.dir.output = fullfile( ...
                                      fileparts(mfilename('fullpath')), ...
                                      'output');

Unclear documentation

now it is 


    fieldsToSet.dir.output = fullfile( ...
                                      fileparts(mfilename('fullpath')), ...
                                      '..', ...
                                      'output');
