New "Clean" Refactor Notes

It is a project that is supposed to help the user to learn foreign languages. There are now plenty of dictionaries available online and finding a translation is no problem. But having seen the translation of a word once does not mean that we have memorized it definitively and the memorization of words and phrases or expressions relies on repetition. The idea is to maintain a database that contains the words to be learned with links to the translation web pages of these words.
