<a name="line-3"></a>A 'Ledger' is derived from a 'Journal' by applying a filter specification
<a name="line-4"></a>to select 'Transaction's and 'Posting's of interest. It contains the
<a name="line-5"></a>filtered journal and knows the resulting chart of accounts, account
<a name="line-6"></a>balances, and postings in each account.
