output and evluation for WikiCatSum

[ShangQingTu]

Hi, Dr. Liu,
Very nice work.
Do you mind sharing your UNILMv2 model's output summaries on WikiCatSum? I mean the predicted target file on the test set.
I don't have much resources to train by myself.
Besides, do you mind sharing your code about the evaluation on WikiCatSum?

Thanks.
