Encipher string using Delastelle cipher according to initialised key.

        Example::

            ciphertext = Delastelle('APCZ WRLFBDKOTYUQGENHXMIVS').encipher(plaintext)     

        :param string: The string to encipher.
        :returns: The enciphered string. The ciphertext will be 3 times the length of the plaintext.
