/*
This is a one-off script that was was used to summarize the results of a
test_sweeper json log file after sweeper.js was run on a particular set of data.
It generates a text file referencing only PRs with any comments/labels
which would have beeen added (test) based on data stored in the
specific JSON log file. You must run sweeper with environment variable
PRODUCTION_RUN set to false, to get the test version.  Technically, you
could also run this on a production_sweeper json log file, if you wanted to see
if the sweeper commented or labeled any PRs during its run.
