Subject: REFL PDs get more light 

After discussions during the meeting today, I removed the PBS from the REFL path, which gives much more light to REFL11, REFL33 and REFL55.  Also, the ND1.5 in front of REFL165 was replaced with ND1.1, so that REFL165 now gets 50mW of light.  REFL11 gets about 1.3mW, REFL33 gets about 13mW and REFL55 gets about 12mW. 

No locking, and importantly no re-phasing of any PDs has been done yet. 

Here is an updated diagram of the REFL branching ratios.
