Return an List of Strings with every String "left shifted" by one -- so ['a', 'abc', 'def', '123', 'y'] returns ['a', 'bca', 'efd', '231', 'y']. Wait, that is too easy. If the first character is a vowel, add it to the end twice, so ['a', 'abc', 'def', '123', 'y'] returns ['aa', 'bcaa', 'efd', '231', 'y']. Yea, this problem does not believe that y is a vowel
