org.auraframework.instance.InstanceStack

A 'stack' of components specifying the position in the tree. This stack is used during component creation on the server to build up and maintain a tree position for communicating with the client. This tree position must exactly match, or everything breaks. Because this is such a sensitive area, we do a variety of very careful checks to ensure that we blow up if there is any indication that we might have gotten out of sync. In an ideal world, we would not have to maintain this because we would know our 'parentage', but that is much easier said than done.
