synopsis.
the "money" group attacks the domain of money finance, and accounting. The objects are fairly simple: money (money_o) is a class for storing and printing money; account (account_o) is for an account element in a chart of accounts, for accounting. It can be of the type asset (A), liability (L), expense (E), income (Y), or [owner] equity (Q). A check entry has these database fields:

id serial,
checking_account int references checking_account (id),
number      int,        # check number
order_idx   int,        # un-#'d transac internal numbering
dr_cr       int,        # 0: cr (w'drawal); 1: DR (debit, dep)
type_codes  char(5),    # up to 5 chars to describe transac
when        date,       # date of check
description char(80),   # who it's made out to
amount      money,      # how much
primary key (id)
