class ReasoningEngine:
    """
    A simple reasoning engine that can evaluate conditions based on predefined rules.
    
    Args:
        rules: A list of dictionaries containing 'condition' and 'action'.
               Condition is a function that takes a state as an argument and returns True or False.
               Action is a function that takes the result from condition evaluation and performs some action.

    Example usage:
        def check_state(state):
            return "green" in state["lights"]
        
        def change_lights(result, state):
