/**
 * @file
 * Adds user profile address support to Ubercart.
 *
 * The uc_addresses module adds support for one or more addresses in
 * the user's profile. When users register, they must provide an
 * address. Users can then add more addresses and edit or delete
 * existing addresses. One address must be designated as the default
 * address and cannot be deleted (but it can be edited).
 *
 * The Ubercart order process is altered so that users select delivery
 * and billing addresses from their collection of addresses rather
 * than from previous orders. Any new addresses entered during the
 * order process are automatically added to the user's list.
