* Initial commit
* Fix bugs
* Need more torque rate
* Cleanup cray cray control
* Write nicely
* Chiiil
* Not relevant for cray cray control
* Do some logging
* Seems like it has more torque than I thought
* Bit more feedforward
* Tune change
* Retune
* Retune
* Little more chill
* Add coroll
* Add corolla
* Give craycray a good name
* Update to proper logging
* D to the PI
* Should be in radians
* Add d
* Start oscillations
* Add D term
* Only change torque rate limits for new tune
* Add d logging
* Should be enough
* Wrong sign in D
* Downtune a little
* Needed to prevent faults
* Add lqr rav4 to tune
* Try derivative again
* Data based retune
* Data based retune
* add friction compensation
* Doesnt need too much P with friction comp
* remove lqr
* Remove kd
* Fix tests
* fix tests
* Too much error
* Get roll induced error under 1cm/deg
* Too much jitter
* Do roll comp
* Add ki
* Final update

* base LatControl class, move sat check out of pid.py
clean up
clean up
* fix
* global variable for min control speed
* nicer name
* unify latcontrol class init arguments
* add to release files
* saturated if close to limit
* move angle mode saturation checks into class
* check_saturation function takes in current saturated status
undo
* apply latcontrol_angle's active checking to all controllers
* clean up
* move those back
* make abstract baseclass
* add test for saturation

* Interpolate ki/kp for steering PID loop
Very much needed for the Volt port: car ping-pongs with low kp
on high speeeds, and the loop is unstable with high kp on
low speeds.
Also, removes "number or array?" logic from PIController,
now that all the callers use interpolation ofr ki/kp.
* Pass speed to steering PID loop for ki/kp interpolation
* Remove unused numbers import
