Added Faraday to Beam Path in CMTF at Fermilab

We added a lens, lambda/4, lambda/2, and a faraday isolator to the beam path on the CMTF table after the EOM. The faraday has 58mW of incident power and 50mW of transmitted power after tuning up the polarization with the waveplates and the beam position relative to the faraday using the lens. Before, we had problems with the beam clipping on the sides of the faraday when we tried to add it to the setup. After these alignment steps, the beam coming out of the faraday looks clean and gaussian -- see the attached image file.
