EY ALS WFS auto-centering

(Sheila Daniel)

Finshed the installation and alignment of the ALS WFS auto-centering for EY. All 4 dofs were engaged. TFs TBD. The first channel of the MCL controller for WFS A seems to have a bipolar input range, whereas all others are unipolar. This is reflected in the applied output offsets of the servo.
