/*** Peter's in code documentation for dummies *********************************
    This is an explanation of the AccountingInformation
    The QString acts as an identifier (hopefully unique....)
    The creditList and debitList objects are structured like this:
        QString  := "account"  || "amount" || "correct"
        QObject* := AComboBox* || ALineEdit* || ABool

    The accountRowInfos are structured like this:
        QString := "accountingNumber" || "date"
        QObject := ALineEdit          || ALineEdit
    NOTE: This is only a AccountingInformation object (no list)

    Example on how to use this crappy thing:
    (qobject_cast<AccountingInformation *>(list->value(int).value("account")))

    Because we get a QList<AccountingInformation>* we need to cast the info
    in order to manipulate the corresponding GUI element (which is one of the
    types mentioned above).
    Contact Fleck Christian for mor details about that.

    We (me and myself) assume that a DataAccountingRecord is identified
    by the accountingNumber only.
