=head2 DESCRIPTION

Tests the prorate_defer_bill behavior when a package is started on the cutoff day,
and when it's started later in the month.

Correct: The package started on the cutoff day should be charged a setup fee and a
full period. The package started later in the month should be charged a setup fee,
a full period, and the partial period.
