// .NAME vtkAreaLayout - layout a vtkTree into a tree map
//
// .SECTION Description
// vtkAreaLayout assigns sector regions to each vertex in the tree,
// creating a tree ring. The data is added as a data array with four
// components per tuple representing the location and size of the
// sector using the format (StartAngle, EndAngle, innerRadius, outerRadius).
//
// This algorithm relies on a helper class to perform the actual layout.
// This helper class is a subclass of vtkAreaLayoutStrategy.
//
// .SECTION Thanks
// Thanks to Jason Shepherd from Sandia National Laboratories
// for help developing this class.
