If we did this, I'd probably want to make the flat account list a
GList or a GArray, and make the "views" into it, a GList (or GSList)
of GLists (or GSLists) which "bottoms out" in Account*'s.

Seem's pretty straightforward, though I believe the point we stalled
at last time was, given this setup, what do account names mean?  Right
now, the full-name is an implicit part of the Group path used to reach
it, but in this "new" approach, an account might appear in a variety
of arrangements.  I think the right answer is that the Account name
would need to be more descriptive, and probably enforced unique,
something like "MegaBank Savings" rather than just "Savings".

Switching to the "flat list" approach would probably be more database
friendly, and it would simplify code that just needs to traverse all
the accounts...
