Initial commit; Simplified Checkout QR code experiment
Undid stupid commit earlier, moved experiment to different folder. Oops.
Added button and methods for ZXing scanning test; need to move Scandit test to new Activity on Monday.
QR Code experiment complete, in simplifiedcheckout folder. NOTE: 'scandit' is a library needed to run the Scandit QR reader.
