    """
    A simple reasoning engine that applies a rule-based approach to solve problems.
    
    This class is designed to address limited reasoning sophistication by implementing basic logical rules and conditions.

    Args:
        problem_domain (str): The domain in which the engine operates. Example: 'finance', 'logic', etc.
        rules (dict): A dictionary where keys are conditions and values are actions to be taken when conditions are met.
    
    Attributes:
        problem_domain (str): Stores the problem domain of the reasoning engine.
        rules (dict): Stores the logical rules and their corresponding actions.

    Methods:
        apply_rules: Applies the rules based on given conditions.
        add_rule: Adds a new rule to the engine.
        remove_rule: Removes an existing rule from the engine.
