Updated (running svn up ${filename} to make sure I didn't get updates to LLO_QUAD_MASTER.mdl or ESD_LINEARIZATION_WITH_CHARGE.mdl)
/opt/rtcds/userapps/release/sus/common/models/
to get 
HLTS_MASTER_W_EST.mdl
ESTIMATOR_PARTS.mdl
SIXOSEM_T_STAGE_MASTER_W_EST.mdl

After looking through their work, I made a few changes.
HLTS_MASTER_W_EST.mdl
    TOPLEVEL
- Changed input signal order to have SUSP signals at the top. Worth the hit in drawing time to match the convention of the top level of SUS models, where the order of sensors comes in by stage.
- Changed name of input ports to be SUSP_ISIGS13_(DOF)_In rather than SUSPOINT_(DOF)_in, again to match convention of (STAGE)_(SENSORTYPE)_(DOF)_In.

    HLTS
- Changed input order of where SUSP point signals come in, putting them at the top, for the same reason.

SIXOSEM_T_STAGE_MASTER_W_EST.mdl
- Cleaned up all of the simulink lines and plusses alone to create an ADDFF block, which now has test points and epics monitors.
- Capitalized "Drives" and "SUSPoint" GoTo tags 'cause I think RCG needs that, and if not it at least looks inconsistent.
- In the ADD block, I changed "(P,Y)_OTHER_MON" to "(P,Y)_ISC_MON"; will need to change your MEDM.
- Added names to the EULMON inputs and output ports

h1isiham2.mdl and h1isiham5.mdl
    TOPLEVEL
- Added IPC senders for pre-calibrated PR3/SR3 SUS POINT projections

h1suspr3.mdl and h1sussr3.mdl
    TOPLEVEL
- Replaced call to HLTS_MASTER.mdl libraryt block with HLTS_MASTER_W_EST.mdl
- Made sure to change part name to PR3/SR3
- Made sure visibility of what blocks are library blocks are turned ON.
- Added IPC reveivers for pre-calibrated PR3/SR3 SUS POINT projections
- Bussed up IPC receivers and piped them over to the main library block
- Changed the constant going in to the ISCINF Filter's LONG bank from 1 to 0. Totally unrelated, to today's work, but it's been a weird quirk of the original top level model for a long time.

SITEMAP
we changed the PR3 and SR3 calls on the sitemap to use SUS_CUST_HLTS_OVERVIEW_W_EST.adl (instead of SUS_CUST_OVERVIEW.adl)

SUS_CUST_HLTS_OVERVIEW_W_EST.adl
Added EULMON in the middle between OSEM2EUL matrix and SENSALIGN matrix
Straighten some lines.


CONTROL_6.adl
we updated P_OTHER_MON to be P_ISC_MON per model change above

ESTIMATOR_OVERVIEW
update S1:SUS-PR3 to be $(IFO):SUS-$(OPTIC)
