## Detailed Description

Specialisation of SceneNode for the BspSceneManager.

This specialisation of SceneNode is to enable information about the leaf node in which any attached objects are held is stored for use in the visibility determination.

  Do not confuse this class with BspNode, which reflects nodes in the BSP tree itself. This class is just like a regular SceneNode, except that it should be locating BspNode leaf elements which objects should be included in. Note that because objects are movable, and thus may very well be overlapping the boundaries of more than one leaf, that it is possible that an object attached to one BspSceneNode may actually be associated with more than one BspNode.
