CEFR levels

It would be nice to introduce a new calculation feature for CEFR levels.

@kupolak I would be interested in contributing. Do you know of anywhere I can find a formula?

@scarroll32 Hi! Sadly, I don't know any formula for CEFR levels. You can try to find lists of A1, A2, B1, C1, C2 words. I think for English it wouldn't be that difficult to find, I don't know about other languages.
And based on that lists you can determine the % of word usage and its difficulty in a text.
