Merge Adam's zeroing updates and add TODOs.

This branch merges some of the updates that Adam got around to with
the version that's on master.

- Remove all code relating to the zeroing queue.
- Use the PotAndIndexPosition structure to initialize the zeroing
  logic.
- Use the PositionSensorSimulator class to test the zeroing logic
  instead of its own internal version.
- Removed the "SimpleStep" test since it was written for a type of
  noise that used the 'floor' math function. We assume Gaussian noise
  in the potentiometer.
