The best way to add things to the memory system is to encapsulate your
component into a SLICC controller.

For example, MOESI_CMP_directory-L1cache.sm is an L1 controller.
MOESI_CMP_directory-L2cache.sm is an L2 controller.  You can add
MOESI_CMP_directory-NEWGIZMO.sm to encapsulate your NEWGIZMO hardware
component into the system.
