<?php
/**
 * this partial is to be used on the listing details page,
 * as well as on the invoice confirmation and shopping cart view pages
 * and basically anywhere where we need a postage calculator box.
 *
 * prerequisites:
 * - the listing must exist in the listings table,
 * meaning that the calculator wont work for the listing preview page
 *
 * required input:
 * - user model [ the seller ]
 * - listing id
 *
 * accepted input:
 * - locationId
 * - postCode
 * - quantity (for a single calculation)
 *
 * result:
 * - a table with all available postage options, or an error message output by the calculatePostage() method.
