Update cli_doPrint.sh:
    
        - Rename it back to cli_printMessage.
    
        - Stop using the `--message' option to hold the message value. The
          message itself is not optional by required in order to print
          something. Instead, start using the first argument as message
          holder.
    
        - At `--as-separator-line', do not draw separator directly to the
          output, but build it in a variable and output the variable value
          instead.
    
        - Only two arguments are valid. One for the message and one for
          the option that modify the way message is printed out.
