Where to obtain lob_excludealltestsets.txt?

Hi, thanks for creating these instructions. In `README.md`, there is a line that says:

```Your team probably has three text files named brown.txt, lob_excludealltestsets.txt and wellington.txt.```

My group has access to Brown and LOB, but we don't know where to obtain `lob_excludealltestsets.txt`. Would you be able to provide some clarification? Thanks.
