Reading the QR Code
The code works as follows
*Set up the camera and QR code detector
*Read in a new frame and extract a QR code
*If there is a code, draw a box around it and display its data above
*If the exit key 'q' hasn't been pressed, go back to step 2.
The program also shows the updated frame with the overlaid graphics on each update.
