Tree Transformer&TreeTransform:
1) using fast tracks in case node type isn't altered by Transformation;
2) using pre-computed hints(nxTransformXXX arrays) to quickly jump to next transformation interested in transforming particular Tree type;
3) using pre-computed hints(nxPrepareXXX arrays) to know which transformations are going to 'prepare' for transforming particular Tree type;
4) recomputing those hints in case some transformation changed implementation class during 'prepare';
5) TreeTransform is now responsible of calling transformFollowing on nodes created by it.
