Constructor

Description

The Node class provides the base functionality for all members of the scene graph representing a world. Most nodes in a scene graph are represented by subclasses of the Node class such as Geometry or Light. When the Node class itself appears in a scene graph, it simply acts as a grouping mechanism and has the kNodeGroup type.

Base Classes

`UpdatableTree<Node>`	Nodes are stored in a hierachical updatable tree.
`Transformable`	Holds the object-to-world transform for a node.
`LinkTarget<Node>`	Used internally by the World Manager.
`Packable`	Nodes can be packed for storage in resources.
`Configurable`	Nodes can define configurable parameters that are exposed as user interface elements in the World Editor.
`Constructable<Object>`	New node subclasses may be defined by an application, and a constructor function can be installed using the `Constructable` class.
