title: Shopify order status not clear
body: <p>I am using shopify admin REST API to fetch status of orders created by customers and admin but there is no single status to check, it has financial status, fulfillment status and sometimes shipping status. An order can be fulfilled if financial status is still pending. Also a restocked item is still showing up as fulfilled. All this is very confusing. I need simple order status like:</p>
  <ol>
  <li>created</li>
  <li>paid</li>
  <li>processing</li>
  <li>fulfilled</li>
  <li>shipped</li>
  <li>delivered</li>
  <li>return in progress</li>
  <li>returned
  how to map shopify order status with above statuses?</li>
  </ol>
