/** @addtogroup Transaction Transaction, Split
A good overview of transactions, splits and accounts can be
found in the texinfo documentation, together with an overview of
how to use this API.
Splits, or "Ledger Entries" are the fundamental
accounting units. Each Split consists of an amount (number of dollar
bills, number of shares, etc.), the value of that amount expressed in
a (possibly) different currency than the amount, a Memo, a pointer to
the parent Transaction, a pointer to the debited Account, a reconciled
flag and timestamp, an "Action" field, and a key-value frame which can
store arbitrary data.
Transactions embody the notion of "double entry" accounting.
A Transaction consists of a date, a description, an ID number,
a list of one or more Splits, and a key-value frame. The transaction
also specifies the currency with which all of the splits will be valued.
When double-entry rules are enforced, the sum total value of the splits
are zero. If there are only two splits, then the value of one must be
positive, the other negative: this denotes that one account is debited,
and another is credited by an equal amount. By forcing the value of the
splits to always 'add up' to zero, we can guarantee that the balances
of the accounts are always correctly balanced.
The engine does not enforce double-entry accounting, but provides an API
to enable user-code to find unbalanced transactions and 'repair' them so
that they are in balance.
Note the sum of the values of Splits in a Transaction is always computed
with respect to a currency; thus splits can be balanced even when they
are in different currencies, as long as they share a common currency.
This feature allows currency-trading accounts to be established.
Every Split must point to its parent Transaction, and that Transaction
must in turn include that Split in the Transaction's list of Splits. A
Split can belong to at most one Transaction. These relationships are
enforced by the engine. The engine user cannnot accidentally destroy
this relationship as long as they stick to using the API and never
access internal structures directly.
Splits are grouped into Accounts which are also known
as "Ledgers" in accounting practice. Each Account consists of a list of
Splits that debit that Account. To ensure consistency, if a Split points
to an Account, then the Account must point to the Split, and vice-versa.
A Split can belong to at most one Account. Besides merely containing a
list of Splits, the Account structure also gives the Account a name, a
code number, description and notes fields, a key-value frame, a pointer
to the commodity that is used for all splits in this account. The
commodity can be the name of anything traded and tradable: a stock
(e.g. "IBM", "McDonald's"), a currency (e.g. "USD", "GBP"), or anything
added to the commodity table.
Accounts can be arranged in a hierarchical tree. The nodes of the tree
are called "Account Groups". By accounting
convention, the value of an Account is equal to the value of all of its
Splits plus the value of all of its sub-Accounts.
