    A simple reasoning engine that can evaluate logical expressions based on predefined rules.
    This class is intended to demonstrate basic problem-solving capabilities within a limited scope.

    Methods:
        - add_rule: Adds a new rule to the reasoning engine's knowledge base.
        - apply_rules: Applies all applicable rules to a given set of premises and returns conclusions.

            - antecedent (str): The condition that must be true for the rule to apply.
            - consequent (str): The conclusion that follows if the antecedent is true.
