Can we use a CSVResultHandler with a
ResultFileDetails.CSV_AGGREGATE_PERFORMANCE? It looks like there is a fair
amount of redundancy with that and the ResultWriter. It makes sense that you
need to wrap the compare logic into this, but result reading and writing should
use the existing framework for that.
