=item C<is_last_billing_date_in_order_value_cycle %params>

Determines whether or not the mandatory parameter C<date>, an instance

of L<DateTime>, is the last billing date within the cycle given by the

order value periodicity. Returns a truish value if this is the case

and a falsish value otherwise.

This check is always true if the billing periodicity is longer than or

equal to the order value periodicity. For example, if you have an

order whose value is given for three months and you bill every six

months and you have twice the order value on each invoice, meaning

each invoice is itself the last invoice for not only one but two order

value cycles.

Otherwise (if the order value periodicity is longer than the billing

periodicity) this function iterates over all eligible dates starting

with C<first_billing_date> (or C<start_date> if C<first_billing_date>

is unset) and adding the order value length with each step. If the

date given by the C<date> parameter plus the billing period length

equals one of those dates then the given date is indeed the date of

the last invoice in that particular order value cycle.
