% function initWorkspaceCaffeTools
% 
% Author: Alexander Freytag
% 
% BRIEF:
%   Add local subfolders and 3rd party libraries to Matlabs work space.
%   Needs to be adapted to your system!
% 
% 
%   Exemplary call from external position:
%        CAFFETOOLDIR   = '/place/to/this/repository/';
%        currentDir = pwd;
%        cd ( CAFFETOOLDIR );
%        initWorkspaceCaffeTools;
%        cd ( currentDir );
