Move logic that was in FLEXLiveObjectsController into FLEXHeapEnumerator. Also adjust FLEXObjectRef initializers to reflect the type of reference you want to hold to the object. FLEXObjectRef now supports unsafe_unretained and retained references.
Also add FLEXMutableListSection which wraps the collection content section in a way that makes displaying a simple list of content straightforward.
Adopt additions in appropriate view controllers.
