Postal Service. You'll need cURL and DOMXML to use the class. */

//domestic shipments and IntlRate for international. Bear in mind that the parameters given for add_package() differ depending on the API you choose.
//You cannot mix and match APIs! If you instantiate the class with RateV2, you must ONLY put domestic packages in your request. (Use the reset() method
//of the class if you want to clear everything, then set $usps->api to the new API you want to use.) Attempts to add packages that do not fit into
//the requirements of the current API will fail.

//Add a package - create an array with the required parameters and send that to add_package.
//Domestic shipments require the following parameters:
//service - Parcel, Priority, Express, First Call, BPM, Library, Media, All
//zip_origin - The originating ZIP code of the package
//zip_dest - The destinaton ZIP code of the package
//pounds, ounces - The weight of the package
//size - Regular, Large, or Oversize
//machinable - true or false, only applies to service types Parcel and All
//Be sure to declare every parameter of the package as a string, or add_package will fail!
//International packages require the following parameters:
//pounds, ounces - Package weight
//mail_type - package, postcards or aerogrammes, matter for the blind, envelope
//country - Must be a full name of a country, in the USPS list of valid countries. Look at the top of the class code for the list.

//added, 1 will be second, etc. If the package you requested returned an error, the error itself will be returned as a string. For here,
//though, we'll assume all went well. If you want to get the FULL error details for a certain package (such as error number and other
//such junk), you can call get_package_error($package_id), which will return an array with the error details.

//API, use one of the following accessor functions:
//get_prohibitions($package_id) - Gets a string containing information about stuff that cannot be shipped to that country
//get_restrictions($package_id) - Gets other restrictions about shipments into that country
//get_observations($package_id) - Gets other, miscellaneous observations about shipments into that country
//get_areas_served($package_id) - Gets a list of the areas served within that country
