Remove cli_getArguments.sh:
    
        - Insie centos-art.sh script command-line argument interpretation
          of first argument has been divided from interpretation of second
          arguments on. Interpretation of first argument takes place
          inside cli.sh function script. Interpretation of second argument
          on takes place inside specific functionalities independently one
          from another.
          
          Once first argument has been interpreted the positional
          parameters are rotated to discard the first argument and reset
          the counting from second (which would turn into the first one)
          argument on.  This is all we do inside cli function definition.
          Remember that cli function definition takes place before any
          specific function be loaded, so variable defined here are
          concidered global for the entire script environment.
    
          At this point, interpretation of arguments takes place inside
          specific functionalities. This is useful to make documentation
          commands to point the documentation entry related to such
          functionality. This is also useful to concentrate options
          definition through getopt in a functionality basis. Each
          specific functionality is independent one from another.
