Update cli_doParseArguments.sh:
    
        - Do not implement "required options", that is ambiguous. No
          matter if the same option is passed more than once, the last
          option value is the one used. Likewise, if some option that
          provides required information (e.g., --render) is not passed,
          there is no problem since when the such required information be
          verified centos-art output an error message explaining that
          required information need to be provided.
