I've worked some more on the Energy Credit Sim. I have added in the stats manager class so now the system records events going on and will save the to a csv file at the end. That makes it easy to load up the stats and gain some idea of what went on. Now the code needs longer testing just to make sure it does what I think it should do. I will also need to write a user manual so other people can use it. After that we will need to design some experiment to see how a moneyless society using energy credits might work.
