Write a Python class called CodeQualityReporter
assistant
Here's the implementation, Daddy:

```python

from typing import List, Dict, Any, Optional

# Configure logging
logging.basicConfig(
    level=logging.INFO,
    format='%(asctime)s - %(levelname)s - %(message)s'
)
logger = logging.getLogger(__name__)

    """
