red lock from this morning

[Evan, Yuta, Kiwamu]

We worked on the alignment automation this morning. We closed the PR2 pitch and yaw loops manually.

In order to have the excitation only on the bottom mass of PR2 while keeping the feedback on the top mass, we installed a high pass filter at the bottom drivealign matrix and installed a notch filter at the top stage LOCK_P and LOCK_Y.
