This should test whether a solution correctly defines which letter is a vowel and which is not. For a pair of letters among which one is a vowel and other isn't, the vowel should be excluded. Otherwise, both letters are kept. Since we can't create a test with 26*26 letter pairs, I added several tests with random pairs.
