    FamilyDomain Class

    Design:
    This class is a specific implementation of the KnowledgeDomain class, providing an 
    implementation for generating responses to family-related questions. Following the 
    Single Responsibility Principle (SRP), its sole responsibility is to generate family-related responses.

    Intended Implementation:
    The generate_response method should generate useful responses to family-related questions. 
    This might involve rule-based logic or a trained machine learning model, depending on the 
    specifics of the problem domain.

class FamilyChain(DestinationChainStrategy):
    """
    FamilyChain Class

    Design:
    This class is a specific implementation of the ChainStrategy class.
    It follows the Open/Closed Principle (OCP) because it extends the ChainStrategy class 
    without modifying its behavior. It also adheres to the Dependency Inversion Principle (DIP) as it 
    depends on the abstraction (FamilyDomain) rather than a concrete class.

    Intended Implementation:
    The FamilyChain class serves as a wrapper around a FamilyDomain instance. It implements the run 
    method from the ChainStrategy class, which simply calls the generate_response method of the FamilyDomain.
    As such, when the run method is called with a question as input, the FamilyChain class will return a 
    response generated by the FamilyDomain.
