A CSGObject has a list of trees (should be branches, must change) which 
each in turn have a list of nodes.  Each node can be scaled/rot'd/grab'd 
(e.g. they each have their own individual rot/scale/loc members).  Also, 
each node is linked to an Object containing a Mesh, so I may change it 
so that the basic rot/loc/size attributes are pulled from that Object.

Each node can also have it's own matrix.  I copied the matrix pointers 
from MetaElem in DNA_meta.h, but I have almost no idea how to actually 
assign a matrix to one.

Ok.

P.S.: Why isn't Link structures used for DNA subobject structs?  The 
whole thing of using struct [subobject] *next, *prev is extreamly confusing.
