    Complete simple configuration initializer.

    This initializer provides a unified setup for basic PyRIT usage including:
    - Converter targets with basic OpenAI configuration
    - Simple objective scorer (no harm detection)
    - Adversarial target configurations for attacks

    Required Environment Variables:
    - OPENAI_CHAT_ENDPOINT and OPENAI_CHAT_KEY

    This configuration is designed for simple use cases with:
    - Basic OpenAI API integration (uses standard OPENAI_API_KEY env var)
    - Simplified scoring without harm detection or content filtering
    - Minimal configuration requirements

    Example:
        initializer = SimpleInitializer()
        initializer.initialize()  # Sets up complete simple configuration
