* @class vtkTreeRingView
* @brief Displays a tree in concentric rings.
*
*
* Accepts a graph and a hierarchy - currently
* a tree - and provides a hierarchy-aware display. Currently, this means
* displaying the hierarchy using a tree ring layout, then rendering the graph
* vertices as leaves of the tree with curved graph edges between leaves.
*
* .SEE ALSO
* vtkGraphLayoutView

* @par Thanks:
* Thanks to Jason Shepherd for implementing this class
