        Obtains a mutable triple of three objects inferring the generic types.

        This factory allows the triple to be created using inference to obtain the generic types.

        Type Parameters:
        L - the left element type
        M - the middle element type
        R - the right element type
        Parameters:
        left - the left element, may be null
        middle - the middle element, may be null
        right - the right element, may be null
        Returns:
        a triple formed from the three parameters, not null
