// .NAME vtkTreeAreaView - 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.
//
// .SECTION Description
// Takes a graph and a hierarchy (currently a tree) and lays out the graph
// vertices based on their categorization within the hierarchy.
//
// .SEE ALSO
// vtkGraphLayoutView
//
// .SECTION Thanks
// Thanks to Jason Shepherd for implementing this class
