* @class vtkTensorProbeRepresentation
* @brief Abstract class that serves as a representation for vtkTensorProbeWidget
*
* The class serves as an abstract geometrical representation for the
* vtkTensorProbeWidget. It is left to the concrete implementation to render
* the tensors as it desires. For instance,
* vtkEllipsoidTensorProbeRepresentation renders the tensors as ellipsoids.
