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

```python

import logging

from typing import List, Dict, Any, Optional

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

        base_url: Base URL for API operations
        composed_capabilities: List of successfully composed capabilities
        errors: Dictionary of failed compositions
    
    Methods:
        compose_capability: Combines multiple simple capabilities into one
        test_composition: Tests a composed capability with sample data
        save_results: Saves composition results to file
