Free period of Warehouse storage before Storage charges begin
Add the ability to support Warehouse Free days against a customer, so that the customer can have "x" number of days before storage charging begins. For example if I charge storage weekly and I give my customer 3 storage free days, if they collect their goods within the 3 days no storage is charged, however if they don't and it falls within the week, they get charged for the week as per normal.
