-- | A multi balance report is a balance report with one or more columns. It has:
--
-- 1. a list of each column's period (date span)
--
-- 2. a list of rows, each containing:
--
-- * the full account name
--
-- * the leaf account name
--
-- * the account's depth
--
-- * A list of amounts, one for each column. The meaning of the
-- amounts depends on the type of multi balance report, of which
-- there are three: periodic, cumulative and historical (see
-- 'BalanceType' and "Hledger.Cli.Commands.Balance").
--
-- * the total of the row's amounts for a periodic report,
-- or zero for cumulative/historical reports (since summing
-- end balances generally doesn't make sense).
--
-- * the average of the row's amounts
--
-- 3. the column totals, and the overall grand total (or zero for
-- cumulative/historical reports) and grand average.
