This will evaluate which elements in the simList object changed following
this Cached function call. It will add a named character string as an
attribute attr(x, ".Cache")$changed, indicating which ones changed.
When this function is subsequently called again, only these changed objects
will be returned. All other simList objects will remain unchanged.
