Alter the Stats.report routine
Alter the Stats.report routine

Use individual files for each Algorithm, because I realized this will
make 5050 (sum(1..100)) lines for each algorithm and that's a lot to
have all in one sheet. I'll figure out how to write multiple discrete
sections into a single CSV file at some point, possibly, and then rejoin
the files into one.

Also emit status updates to stdout unless suppressed with verbose: false
