Remove `path' functionality from centos-art.sh script. 
    
        - Instead, functionalities that relay on path information to do
          their works (e.g., help) need to implement their own way to
          copy, delete and rename files related to them.
          
        - Later, higher functionalities will call specific functionalities
          to realize the file movement inside the repository, as well as
          any path transformation that can be realized on higher
          functionalities to avoide unnecessary use of file movement
          actions inside specific functionalities. 
          
        - This configuration is required because specific functionalities
          work with specific information that can't be set on higher
          functionalities. This is, because they are very specific to one
          functionality.
