MAIN QR CODE FEATURE: Be able to generate a unique QR for for a registrant object so they can be checked in as "Attended" a the EVENT LEVEL. Early version is a workflow action made for registrant record, zero configuration needed, just generates it and plops the URL of the image into a single line text field. Ideally we would also need a Email module that will show the property. When Custom Object Webhooks become a thing, we then just do it automatically with no workflow needed.

Secondary QR code feature: A workflow action that works on any object to create a QR code that goes to a URL. You would select a single line text field on any object to grab the URL from, and then select a 2nd single line text field to plop the URL of the generated QR code image into.
