    """
    A basic reasoning engine that solves a specific problem of limited reasoning sophistication.
    
    This class provides a simple mechanism to evaluate logical rules and apply them to given conditions.

        Add a new logical rule to the engine.

        Parameters:
            rule (str): A string representing a logical rule in the format 'condition1 and condition2 => conclusion'.
        
        Example usage:
