Update Evaluation used for V.1.1.1

[jordiclive]

The references in /evaluation/dart_reference are not for the current version. Can you replace with the new references and share the tokenization script that is done to the predictions.

I am getting very different BLEU scores depending on tokenization, and how many references I use. As there are up to ~30 for a few examples.

I would like to directly compare against the README leaderboard.

How to run BART in the model. Could you provide more details about running environment and python script.
