docs: initializes a base logger
  
      you can use this to init a logger in any of your files.
      this will use config.py's LOGGER param and logging.dictConfig to configure
      the logger for you.
  
      :param int|logging.LEVEL base_level: desired base logging level
      :param int|logging.LEVEL verbose_level: desired verbose logging level
      :param dict logging_dict: dictConfig based configuration.
       used to override the default configuration from config.py
      :rtype: `python logger`
