I'm afraid Get*Language gives a wrong impression (even though we'll document
about that). How about DetectTabLanguage() to make clear that it's not for
reading off the value of 'lang' or 'xml:lang' or 'Content-Language'?

Also, CLD returns the top 3 languages with the proportion of each in the input.
It appears that this function just returns the top language. Do we want to have
another function for a more advanced usage?
