Lab---Piratizer.

Because in the stringTransformer the text is changed by words, so I cannot use '.' or ',' to control if this is the end of the sentence. So I change this into every time I get a Uppercase letter I consider it is the beginning of a sentence, so the char before is the end of the sentence then I can put "Ahoy" or "Arrrr". The only problem is that words like "Darkness" or "Light" is Uppercase letter as well....

And I cannot write a complete test because the output is random.
