NetConfig now has an option for the configuration to be randomly generated on the fly from a ConfigRange, as opposed to Evaluator randomly sampling 12 configs (thus a single config vector can contain random and non-random configs). I'm not sure whether this is the right way to go but it seems to me that Evaluator shouldn't need to know how the configurations are generated.
program which trains and tests in one shot (batch-runner) and script to run this on several configurations (batch_test.sh) added to quickly run tests on various congestion signals; constants file added to easily exclude/include certain congestion signals.
