This isn't actually a sub-module, but really a bunch of potential changes to the shop system.

• Shop module v0.9

• Put the shop_shippingframework folder into your SilverStripe root directory
• Add the ShippingFrameWorkModifier to your modifiers config, eg:

    Order::set_modifiers(array(
        'ShippingFrameworkModifier',
        'FlatTaxModifier'
    ));

• You need to use the new SteppedCheckout system to allow customers to set their address before they choose their shipping method. To set up steps, including the shippingmethod step, add the following to your mysite/_config.php file:

    SteppedCheckout::setupSteps(array(
		  'membership' => 'CheckoutStep_Membership',
        'contactdetails' => 'CheckoutStep_ContactDetails',
        'shippingaddress' => 'CheckoutStep_Address',
        'billingaddress' => 'CheckoutStep_Address',
        'shippingmethod' => 'CheckoutStep_ShippingMethod', //extra line for shipping method
        'paymentmethod' => 'CheckoutStep_PaymentMethod',
        'summary' => 'CheckoutStep_Summary'
    ));

• To add the shipping estimation form to your CartPage template, add the following somewhere on your CartPage.ss template:

    <% include ShippingEstimator %>

If you need some example tableshipping data to populate your site for testing/development, you can run the task: yoursite.tld/dev/tasks/PopulateTableShippingTask

ShippingPackage is a class used to encapsulate shipping data including: weight, dimensions, value, quantity.

ShippingMethod is the base class for different types of shipping calculation. These could either be flat rates, table based rates, or a

TableShippingMethod has many TableShippingRate, where TableShppingRate extends RegionRestriction. Table shipping rates also have optional weight, volume, value, and quantity constraint fields.

The RegionRestriction class serves as a base class for providing regionalised restrictions. Restrictions are specified by Country, State, and PostalCode. A value/rate can be given to each restriction. To work the appropriate rate, query for all the matchign restrictions, and sort by cheapest.

The wildcard '*' means the restriction will match any region.
