ReCoRD dataset

[markus583]

It is not clear how you deal with the ReCoRD dataset - the collater, metrics, and so on. In your final version, do you use the SuperGlueDatasetForRecord or just the regular SuperGlueDataset? It is really unclear.

If have tried both and also tried to fix some of the errors involved but have not found a way to work it out.
It would be highly appreciated and very helpful if you could specify this a bit. Thanks!
