  """ This class allows to work on getting your Argparse object
      ready even if nothing useful happens when used.
  
      Save this git on some file then import the class.
  
      Usage:
      Just set action=NotImplementedAction when calling add_argument, like this:
  
      import argparse
      parser = argparse.ArgumentParser()
      parser.add_argument("--missing",
                          help="This will do something in the future",
                          action=NotImplementedAction)
