+Takes one or more bank transaction ID (as parameter C<form::ids>) and
+tries to revert all payment bookings including already cleared bookings.
+
+This method won't undo payments that are in a closed period and assumes
+that payments are not manually changed, i.e. only imported payments.
+
+GL-records will be deleted completely if a bank transaction was the source.
+
+TODO: we still rely on linked_records for the check boxes
+
+=item C<convert_purpose_for_template>
+
+This method can be used to parse, filter and convert the bank transaction's
+purpose string before it will be assigned to the description field of a
+gl transaction or to the notes field of an ap transaction.
+You have to write your own custom code.
+
+=item C<_check_and_book_credit_note>
+
+This method takes a array of invoices with two entries one one valid credit note
+and books the amount of the credit note against the invoice via the default
+transfer items account (i.e. SKR04 1370) and adds a source and memo entry for the
+payment booking.
+Logical and visual linking of the payment booking and credit note record to the bank
+transaction will also be done (necessary cond. for unlinking a bank transaction).
+If the methods success the credit note will be deleted from
+the original caller's array and he can further process the data without pondering
+about the removed credit note data.
