Corrections

This release includes the removal of the Sacks for Market Mail and Periodicals Flats and SCF Pallet Discount for Market Mail Flats. As part of the USPS network redesign efforts, the Postal Service is eliminating the use of sacks as containers for Flats acceptance/entry. They will continue to allow Flat trays as an acceptable container for acceptance and entry along with bundles on pallets for USPS Marketing Mail and Periodicals Flats Mail. Carrier Route, 5-digit Scheme Carrier Routes, and 5-digit Carrier Routes USPS Marketing Mail and Periodicals Flat mail will continue to use sacks as a handling unit. 

This release adjusts the code for the Carrier Route to produce the expected results correctly.
