// .NAME vtkAreaLayoutStrategy - abstract superclass for all area layout strategies
//
// .SECTION Description
// All subclasses of this class perform a area layout on a tree.
// This involves assigning a 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).
//
// Instances of subclasses of this class may be assigned as the layout
// strategy to vtkAreaLayout
//
// .SECTION Thanks
// Thanks to Jason Shepherd from Sandia National Laboratories
// for help developing this class.

// (innerRadius, outerRadius, startAngle, endAngle).
// For rectangular layout, this is
// (xmin, xmax, ymin, ymax).
