Public Member Functions
	bart_node ()
	a simple default ctor

	bart_node (const bart_node &cp)
	a copy ctor shallow copy.

void	list_all_nodes (vector< bart_node * > &all_nodes)
	populating all_nodes with flatted array of all nodes from current node including this node.

int	depth ()
	returning node depth

float	variance (const vector< float > &y)
	calculating node variance in the observations in the node

void	deep_clone (bart_node *&target)
	deep copying of the node and all it's acendents by allocating new copies of all nodes

void	print_tree (const vector< vector< float > > &feature_sorted_values) const
	printing tree from current node

void	validate_tree (const vector< vector< float > > &feature_sorted_values, const vector< float > &x, int nftrs) const
	for debug - validating the tree structure is correct with childs\parents pointers and that the observations in each nodes are correct.
