[vos-d] More new S5 classes/concepts

[Reed Hedges]

I'm going through S5 a bit more deeply now.

Pete, can you give a summary explanation of these new classes/concepts, 
and how you use them, what they do, etc.

What are:
   ComponentWrapper
   Promise
   Status (used with a Promise it seems?)
   IVobject
   VobjectImpl
   ImplementationWrapper
   ImplementationComponent
   ConstructorFunctionWrapper
   ConstructonFunctionFunctor
   ConstructorFunctionComponent
   The host's factory (i.e. from Host::getFactory())
   ParentChildLinkWrapper
   the "SITE_...blahblah..._NAMESPACE" namespace
   DataType
   DataTypeWrapper
   Class
   ClassWrapper
   the "vos:abcdefg12345...[1]/foo/bar" strings that appear various places
   What is something's "owner" (i.e. the getOwner() virtual methods that 
lots of classes have)

What kinds of things are generated by the code generator, and from what 
bits of information?

Can you explain 'MVC' a bit more (it seems to now be part of the library?)

In interreality3D, how does it use MVC? What is, for example, an object 
like wxMultiframeContextWrapper and wxMultiframeContextComponent?  What 
is the wxgui namespace.

What does it mean to append children to the local host?  I am guessing 
this is so the object doesn't get destroyed (by reference count/garbage 
collection), and so you can also obtain it by name later?  Do all 
objects need to be added to the local host (like they were all children 
of the local site in s4)? And if so, why not do that automatically when 
created?

Can you explain more these changes to A3DL? What is a scene, what is a 
render layer, clock, node, etc.?


I'll start a NewStuffInS5 wiki page or something, including some of the 
previous discussion on vos-d.
