Recently, the 
${userapps}/release/sus/common/models/SIXOSEM_F_STAGE_MASTER.mdl
had been updated in order to include signal exchange and CART2EUL and EUL2CART transformation with the ISI signals. Because the TMTS models use this library part, the 
${userapps}/release/sus/common/models/TMTS_MASTER.mdl
main library part, and the top level model,
${userapps}/release/sus/h2/models/h2sustmsy.mdl
needed to be updated to handle these new input and output ports.

I've done so on both the above mentioned models, and recompiled to ensure functionality (and was successful). Since this is an unimportant change, at the advice of Alberto, Dave and I agreed to just reinstall, restart, and restore the model during next Tuesday's (July 31 2012) maintenance period.

Further Notes:
---------------
- the original motivation and discovery of the problem was because Dave has noticed that the 
/opt/rtcds/lho/h2/chans/ipc/H2.ipc
(the file that stores the channel mapping for inter-process communication) had a whole bunch of old crap in it, so he deleted it, and wants to recompile all models that use IPC in order to refill it.

- These changes were made in parallel with other changes to top level models. Unfortunately, the commit log message that was intended for the h2susitmy commit 

- I've also added EPICs output channels which capture the IPC receive errors, called
H2:SUS-TMSY_ISC_IPC_PIT_ERR
H2:SUS-TMSY_ISC_IPC_YAW_ERR

which eventually can/should be included somewhere in MEDM screens.
