public class Node
extends Object
```
A node is a value to process in the BFS. It also links children to parents to ensure hierarchy in variables.

Nested Classes
Modifier and Type	Class	Description
`static interface`	`Node.IConsumer`	The consumer of the nodes when running a BFS.
`static interface`	`Node.IParent`	The parent of a processed node.
`static class`	`Node.NodeValue`	This type wraps an Object that we are to process.

Constructors
Constructor	Description
`Node(Node.NodeValue value, Node.IParent parent)`	Create a new node for the BFS.
`Node(Node.NodeValue value, Set<Node> children, Node.IParent parent)`	Create a new node for the BFS.

public static void breadthFirstSearch(Node root,
                                      Node.IConsumer consumer)

Start the breadth first search of the nodes.

Parameters:: root - the root node to start from; consumer - the consumer to use to collect more nodes.
