Detailed Description
A LetterTokenizer is a tokenizer that divides text at non-letters.That's to say, it defines tokens as maximal strings of adjacent letters, as defined by java.lang.Character.isLetter() predicate.
Note: this does a decent job for most European languages, but does a terrible job for some Asian languages, where words are not separated by spaces.
