// .NAME vtkTensorProbeWidget - a widget to probe tensors on a polyline
// .SECTION Description
// The class is used to probe tensors on a trajectory. The representation
// (vtkTensorProbeRepresentation) is free to choose its own method of
// rendering the tensors. For instance vtkEllipsoidTensorProbeRepresentation
// renders the tensors as ellipsoids. The interactions of the widget are
// controlled by the left mouse button. A left click on the tensor selects
// it. It can dragged around the trajectory to probe the tensors on it.
//
// For instance dragging the ellipsoid around with
// vtkEllipsoidTensorProbeRepresentation will manifest itself with the
// ellipsoid shape changing as needed along the trajectory.
