* @brief Manages a list of vtkGeoTreeNodes.
*
*
* vtkGeoTreeNodeCache keeps track of a linked list of vtkGeoTreeNodes,
* and has operations to move nodes to the front of the list and to
* delete data from the least used nodes. This is used to recover memory
* from nodes that store data that hasn't been used in a while.
