Detailed Description

lays out tree in stacked boxes or rings

Performs a tree ring layout or "icicle" layout on a tree. This involves assigning a sector region to each vertex in the tree, and placing that information in a data array with four components per tuple representing (innerRadius, outerRadius, startAngle, endAngle).

This class may be assigned as the layout strategy to vtkAreaLayout.

Thanks:: Thanks to Jason Shepherd from Sandia National Laboratories for help developing this class.
