Deferred Revenue Recognition -- Part II

It turns out the rate flag is not reliably set for all cases, but it is set for certain cases. I just have to make certain assumption when I can't figure out its value. It happens for the very first cycle charge, which helps since I know the context of the first cycle. Anyway it looks like I can get this feature to work on 7.2, admittedly it is not easy. But hey no pain no gain :)
