wrote competitive tests (the always climbing is a bit iffy) and then finished the learning increase/decrease. Unfortunately they don't seem to work well in competitive settings (everybody is a monopolist there, which is funny but wrong). Also the supply chain tests simply take too long. I am moving back to LinearExtrapolator, but maybe I can combine the two. Priority should be given in having small regressions, and not too often!
rearranged the way markets store data. That was just a lot of pain for no gain
