>Subject: [PATCH] Bug 13106 - Encapsulate Circulation::GetAgeRestriction() and
> modify it to check borrowers age as well.
>
>This patch moves the logic of deciding whether or not a borrower is old enough to access this material
>to its own function GetAgeRestriction.
>
>This makes it easier to use AgeRestriction elsewhere, like with placing holds.
>
>This feature adds a new function C4::Members::SetAge() to make testing ages a lot easier.
>A ton of Unit tests included.
