ContainerHierarchy again

At the last meeting there was a resolution to move back to the previous positon 
on container hierarchies, the position called "the minimal consensual position"
in 

   https://www.w3.org/2012/ldp/wiki/ContainerHierarchy

But that wiki page shows how the minimal consensual position we have currently
+ the decisions we have previously come to lead to hierarchy

In RDF subclass relations DO NOT mean dependence of one subclass
on another. You can easily deprecate classes without subclasses or
superclasses without this leading to legacy issues.

All the subclass relations mean is that you cannot have objects that are in one
class and not the superclass as shown by the picture

So I think it is misleading in fact to now show the classes as having no relation to each
other when we know they do.
