Simulink model and MEDM screen for AA is now completed and ready to be tested with quadrants.

Note: while restarting the model last sunday I was not able to restore the screeshot file taken just before the restart. I didn't find any problem with the command but some of the epics channels remained blank. I check the file and see that some of that channels ware actually missing. I don't know why it happend. Anyway I restored a previous snapshot file. I restarted the model and restored snapshot several times after that and this problem never showed up again.
