// .NAME vtkGraphLayoutStrategy - abstract superclass for all graph layout strategies
//
// .SECTION Description
// All graph layouts should subclass from this class. vtkGraphLayoutStrategy
// works as a plug-in to the vtkGraphLayout algorithm. The Layout()
// function should perform some reasonable "chunk" of the layout.
// This allows the user to be able to see the progress of the layout.
// Use IsLayoutComplete() to tell the user when there is no more layout
// to perform.
//
// .SECTION Thanks
// Thanks to Brian Wylie from Sandia National Laboratories for adding incremental
// layout capabilities.
