All <class> tags and vtable="" attributes in Memory.xml are now obsolete.
<multiclass> tags are still important, but don't need the vtable attrs.
Vtables are resolved automatically.
All this will be left in Memory.xml until utility authors update to this version or newer.
Tools are now useful, and with a working user interaction where applicable.
Examples are a collection of benchmarks, tests and simple unfinished ideas.
