lab2: the beginnings of lab2 reusing code from lab1
lab2: Integrate motor controller code from first assignment (no PD control)
lab2: basic PD controller working but with no way to change target position

This appears to be working, at leat to some degree as when you try to
twist the wheel it "fights back" like it should.
lab2: add cli interface, better lcd display, and other cool stuff
lab 2: first attempt at making the motor control be drive by custom PWM code
lab2: PWM is now working driven directly by code written to register set

This is using fast PWM.
lab2: add cli commands and features (some not implemented yet)
lab2: add support for live-logging of pd controller state
lab2: add support for view command
lab2: add inital code to support different service rates and fix view logic
lab2: incorporate updated deque code from simpleds (https://github.com/posborne/simpleds)

This will be used (hopefully) for building a correct serial implementation
that does not block (usually).
interpolator: first pass at interpolator (not working yet)
lab2: progress toward working linear interpolator (has bugs)
lab2: linear trajectory interpolator with target destination queue working
lab 2: prep for lab writeup by adding section to README.md for lab
lab2: progress toward completing the writeup and related tweaks
lab2: final parts of lab writeup now present with assets
lab2: fix indentation of block
lab2: resize graph and play around with pandoc gen to other formats
