// .NAME vtkCirclePackLayoutStrategy - abstract superclass for all circle packing
// layout strategies.
//
// .SECTION Description
// All subclasses of this class perform a circle packing layout on a vtkTree.
// This involves assigning a circle to each vertex in the tree,
// and placing that information in a data array with three components per
// tuple representing (Xcenter, Ycenter, Radius).
//
// Instances of subclasses of this class may be assigned as the layout
// strategy to vtkCirclePackLayout
//
// .SECTION Thanks
// Thanks to Thomas Otahal from Sandia National Laboratories
// for help developing this class.
