I've been busy coding a Nixie Tube library, which is the first of [what I think will be] three libraries in total, along with the main program that will orchestrate everything. The other two libraries will be Nixie Driver and Nixie Display. These will work together to model the physical objects in code.

This initial test demonstrates that PWM is working correctly on the red LED, and BCD counting 0 to 9 is working correctly on the green LEDs.
