changing G2

I really want to add true Ledger Entries, so I've made it central to G2, pushing everything except the calendar generator into a separate generation. This will give us improved list handling and a good way to work with spreadsheet data.

(Think about setting up the applicative context so that the visible ledger entries compose an interesting list that can be exported to a spreadsheet.)

With the new CompStrm-2, we begin to realize more of the rolonic capabilities. Its a lot more than a Wiki--that's just the user interface.

I've updated the CompStrm to reflect the new G2: http://compstrm.sourceforge.net/
