ledger-litelisted

# Ledger lite 1. Read the amount, the date and the counterparty off whatever was handed over. 2. Append one row to `ledger.csv` in that order. Stop when the row is written. 3. Print the new balance, with the currency, on its own line. ## When to open which reference [format.md](references/format.md) holds the column order and the rounding rule. Open it before writing a row; the input's own layout never decides the column order.
