BBSS SUS medm infrastructure filled in

I've gone through and filled in most of the infrastructure for the BBSS (found under BS/ITM on sitemap as BBSS temp). Values and filter settings have been saved to sdf and filters added have been committed in H1SUSLO12.txt as r35219. For the majority of the filters banks, I turned any filters that are shown as being on in whatever I referenced them from, but all filter banks have INP and/or OUT OFF, so no signal can pass through.

Infrastucture filled in:

All stages
OSEM2EUL / SENSALIGN / EUL2OSEM Matrices
Filled out according to matrices calculated in /ligo/svncommon/SusSVN/sus/trunk/BBSS/Common/MatlabTools/make_susbbss_projections.m. The Y direction matrix elements for M1 OSEM2EUL have been left blank for now

M1
OSEMINF Filter Banks
- _{F1,F2,F3,LF,RT,SD}_{X_RAW,Y_RAW,SUM} have satamp compensation filter of zpk([0.145],[720e-6],1) installed in FM1, called 0.15:7e-4
- _{F1,F2,F3,LF,RT,SD}_{X,Y} have a conversion from counts to um with a gain(250) in FM5, called to_um. This value was found by using the conversion from Tom of 4000 counts / meter, and then converting meters to um.
- Tom said that we will not need any offsets, and the QOSEMs are calibrated so we don't need any special gains in the filter banks, so I've set the filter banks to gains of 1.
WATCHDOG Filters
BANDLIM Filter Banks
- Same filters as in OSEMINF, plus acBandLimiter
RMSLP Filter Banks
- 10 second LP added into FM1
LOCK Filter Banks
- Copied over from BSFM M1 for now
DAMP Filter Banks

M2
OSEMINF Filter Banks
- Satamp precise compensation filters inserted into FM1 according to the installed satamp for M2, plus conversion to_um in FM5
- Offsets and gains need to be re-done for BBSS M2
