Added "get_rates" (3 tools before, 4 now)
Compare shipping rates — Shipping prices for one parcel between two postal codes from USPS, UPS and FedEx, cheapest first, with delivery days and surcharges. Each quote names its source and rateType (retail, list, or a postage reseller's price). Quotes only: nothing is bought and no label is made. Sources that can't quote come back in errors.
