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

```python
import logging
from typing import Dict, List, Optional, Any
import yaml
import json
from datetime import datetime

class AttentionController:
    """
    Controls selective attention based on goal priorities and environmental salience.
    
    Attributes:
        world_model: Instance for reasoning about environment
        behavior_history: Last 100 focus decisions
        focus_weight: Current weight influencing focus selection
        goals_salience: Goal priorities (salience scores)
        world_state: Current environmental state
        checkpoints: Time-based memory checkpoints
        
    Methods:
        update_salience: Update salience scores based on world model
        set_focus_priority: Set priority for specific actions or concepts
        get_recommended_focus: Return most salient focus point
        register_observation: Update world state from new data
        save_checkpoint: Create timestamped memory snapshot
    """
