setting up code to diff ffld and voc5
experimenting with csvdiff ... doing some tweaks
FFLD and VOC5 match reasonably well. with a diff threshold of 0.1, there are ~5% differences. This is true for all BUT the top level. At the top level (hog(1) in voc5, hog(0) in FFLD), there are a lot of differences. not sure what's causing this. need to dig deeper.
