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

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

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

class TrainingDataCurator:
    """
    A tool to curate training data for AI models.
    
    Attributes:
        dataset_path: Path to the raw dataset file
        output_file: Name of the curated training file
        max_examples_per_topic: Maximum examples per topic
        seed: Random seed for reproducibility
        
    Methods:
        load_dataset(): Loads and parses the dataset
        extract_topics(): Finds relevant topics from texts
        select_optimal_examples(): Chooses optimal training pairs
        save_training_data(): Writes selected data to file
