 The formatter should lie in `src/Laravelrus/LocalizedCarbon/DiffFormatters` directory, following a simple naming convention: the class name should start with the desired language in lower-case, but the first letter in upper-case. The rest part of the name should be "DiffFormatter". The file name should correspond to the class name.
 
 For example, the formatter for `fr` language would lie in `src/Laravelrus/LocalizedCarbon/DiffFormatters/FrDiffFormatter.php`, and the class name would be `FrDiffFormatter`.
