Create a logical view node.
Projects should not attempt to cache this node in any way;
this call should always create a fresh node with no parent.

The node need not bother implementing badging
for the root node; any files contained in the project will
be considered as badging sources automatically. Other subnodes representing
various collections of files may still need explicit badging logic.
