Another refactoring session:

o mk_cache_id() obsoleted by removing the node index from the dump
o node index output removed from each node and make optional in NodeDumper
o The visitors are no longer global, but associated with a tree
o Added Tree class to manage node trees and the (now implicit) dump cache
o Moved PolySet cache into PolySetRenderer
