Notes and Changes:
V2 Change: ATF and Precision Photonics have since merged so our second vendor to bid for the high quality viewport optic will be FiveNine Optics.

V3 Change: 3rd General Access Port added (#20 on HAM7 -Y Door) per request by Robert Schofield.

V4 Change: CVI added to vendors list for glass (per Peter's suggestion), #12 port moved in layout to better represent positioning, and #19 port moved from -X door to -Y door for better view of the HSTS and easier access (per Lee's suggestion).
