config: Add SubSystem container for simobjects
This patch adds the SubSystem container for grouping simobjects together in logical subsystems to facilitate building a larger system from constituent parts. The container is simply a non-abstract empty simobject to hold the components that will be connected as its children. In simulation the object does not participate, its only use is during configuration of the system.
