Calibration utilities

[ghost]

For:

• aiming a range sensor with the IR camera
• fitting a function for range [ raw reading -> distance ] conversion
• streaming sensor readings (encoder, gyro, range)
• tuning linear/rotational feed-forward acceleration/velocity (should accomodate different conditions, e.g. different paths or speeds)

Should be standalone tools that can easily be "turned on" or dropped into main() for easy use. When possible or convenient, should use menus or button presses for quick adjustments or re-runs.
