Code for the EdgyCam kiosk

The kiosk is a cabinet that contains

1. A Raspberry Pi computer
2. A USB webcam
3. A video monitor
4. A receipt printer
5. A big red button

Users stand in front. The webcam is looking at them. On the screen is displayed a full screen image of the scene turned into a line drawing using the openCV.canny (https://pypi.org/project/opencv-python/). When the big red button is pressed, the image is printed on the receipt printer.
