// .NAME vtkPVComparativeAnimationCue - cue used for parameter animation by the
// comparative view.
// .SECTION Description
// vtkPVComparativeAnimationCue is a animation cue used for parameter
// animation by the ComparativeView. It provides a non-conventional
// API i.e. without using properties to allow the user to setup parameter
// values over the comparative grid.
