Case contract

Input {count_value, period_end, items:[{type, terms, value, shipped_day, arrived_day|None}]}. Goods "arrived" when arrived_day is set and <= period_end. Inbound in transit is added when FOB_shipping, shipped by period end and not arrived. Outbound in transit is added back when FOB_destination, shipped by period end and not arrived. Goods consigned out are added; consigned-in and bill-and-hold goods (counted but not owned) are subtracted regardless of terms. Return {adjusted, adds, subtracts}.
