    A basic reasoning engine designed to solve problems with limited reasoning sophistication.
    
    This class implements a simple rule-based system where rules are stored as dictionaries and can be applied
    based on certain conditions.

    Methods:
        add_rule: Add a new rule to the engine.
        apply_rules: Apply all applicable rules given an input state.

            condition (callable): A function that takes the current state as input and returns True if the rule applies.
            action (callable): A function that defines what should be done when the rule is applied.
