I've added a new directory in /opt/rtcds/caltech/c1/core called rts_simlink.  This directory is now in the 40m svn.  Unfortunately, the simlink files used to generate the front end c codes live in a directory controlled by the CDS svn.  So I've copied the .mdl files from /opt/rtcds/caltech/c1/core/advLigoRTS/src/epics/simLink/ into this new directory and added them into the 40m svn.  When making changes to the simlink files, please copy them to this new directory and check them in so we can a useful history of the models.
