class_docstr: Simple implementation of ArgumentParser supporting config file
  
  This class is originated from https://github.com/bw2/ConfigArgParse,
  but this class is lack of some features that it has.
  
  - Not supporting multiple config files
  - Automatically adding "--config" as an option.
  - Not supporting any formats other than yaml
  - Not checking argument type
code: def __init__(self, *args, **kwargs):
      super().__init__(*args, **kwargs)
      self.add_argument(
          "--config", help="Give config file in yaml format"
      )
  
imports: import argparse
  from pathlib import Path
  import yaml
label_desc: Use image node_id 1 to create a new ArgumentParser object from inherited base classes: argparse with example: obj = ArgumentParser()
