// .NAME vtkSeedRepresentation - represent the vtkSeedWidget
// .SECTION Description
// The vtkSeedRepresentation is a superclass for classes representing the
// vtkSeedWidget. This representation consists of one or more handles
// (vtkHandleRepresentation) which are used to place and manipulate the
// points defining the collection of seeds.

// This method is used to specify the type of handle representation to use
// for the internal vtkHandleWidgets within vtkSeedWidget. To use this

// this method with this dummy. Then the vtkSeedRepresentation uses this
// dummy to clone vtkHandleWidgets of the same type. Make sure you set the
// handle representation before the widget is enabled.
