Run EinkPaper.py to start the program. To run in test mode, add argument -t or --test.
Test mode will save generated images to the working directory rather than export them to an external display.
Test mode will auto run if no external display package is detected.

EinkPaper.py will construct widget classes from widgets.py. Widgets are constructed in the initWidgets() function in EinkPaper.py.

The image widget is currently set to resize (to fit the whole image on the widget w/ no cropping), then to either monochrome or greyscale dither the image as specified in initWidgets(). The zoom function is currently broken and to be fixed.
