// .NAME vtkGeoTreeNodeCache - Manages a list of vtkGeoTreeNodes.
//
// .SECTION Description
// 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.
