Google Autofill for Shift4Shop Admin

This extension allows Google Address Autofill integration for Shift4Shops on AmericasBelting.com website only. Shift4Shops admin does not have native support for Google Address Autofill on customer pages to verify street address information when an order taker enters the billing and shipping address for a customer. The code will inject a javascript for admin URLs hosted on a specific Shift4Shop store used by Americas Belting that makes XHR API calls to the Google Address Autofill backend to request the correct address based on the USPS address information and insert it into the admin order page when taking an order. As the employee types the address, it will automatically fill the corrected address information into the form on the admin order page. The code also creates id tags on the address fields in order to allow the Google Address Autofill code to find the appropriate fields for both shipping and billing addresses to insert the information into the correct location on the form. The only users that will install the code are users who work for Americas Belting. If a user was to install the extension for other domains, they would not have access to any valid code since the extension is only allowed to execute on our specific store domain. Google Address Autofill also has a key specific to americasbelting.com to only allow requests from that domain.
