		const PR &
	)

Initialize, set the number of trees

void reset_tree

(

int

tree_id

)

Reset a tree

void visit_after_tree	(	RF &	,
		PR &	,
		SM &	,
		ST &	,
		int
	)

simply increase the tree count

void visit_internal_node	(	TR &	tr,
		IntT	index,
		TopT	node_t,
		Feat &	features
	)

do something when visiting a internal node during getToLeaf

remember as last node id, for finding the parent of the last external node also: adjust class counts and borders
