Further tweaked the code to add new transactions, primarily by creating separate verification and addition functions in each underlying model. There are logic changes as well, such as adding in the other half of the missing double entry (as well as the double entry itself). This checkin also introduces the creation of CREDIT statement entries, when the customer has overpayed. It's working fairly well, although undoubtedly will need more tweaking.
