reporting performance from model runs

[abfleishman]

I could see it being really useful to instead of making a new csv with performance each time you train a model to actually append the new run to the same csv.

I would love a table that had a summary of the training run. Maybe a csv with

1. date/time of run,
2. number of training images,
3. number of each class,
4. performance on the cross val or test data (recall and precision and maybe to numbers of FP, TP, FN, TN)
5. mAP for each run
