The Settings class in the hana_ml.algorithms.pal.utility module is used for configuring the logging level, loading HANA credentials, and setting the logging level with parameters such as 'info', 'warn', 'debug', and 'error'.
------
Here is a Python code template based on the provided documentation:

```python
class Settings(object):
    """
    Configuration of logging level
    """
    settings = None
    user = None

    @staticmethod
    def load_config(config_file, tag='hana'):
        """
        Load HANA credentials.
        """
        pass

    @staticmethod
    def set_log_level(level='info'):
        """
        Set logging level.
        
        Parameters
        ----------
        level : {'info', 'warn', 'debug', 'error'}
        """
        pass
```

This is a basic template and does not include any actual functionality. You would need to fill in the `pass` statements with your own code.
