	pub fn layer_item_id(&self, level: usize, item: usize) -> usize {
	if level == 0 {
	item
	} else {
	self.layers[level][item as usize].zero_node
	}
	}

This indexes layers with level where all other methods seem to use level - 1 here to compensate for the zero layer being stored in its own vector. This means that the feature for an unexpected node ends up being looked up.
