* @class vtkHedgeHog
* @brief create oriented lines from vector data
*
* vtkHedgeHog creates oriented lines from the input data set. Line
* length is controlled by vector (or normal) magnitude times scale
* factor. If VectorMode is UseNormal, normals determine the orientation
* of the lines. Lines are colored by scalar data, if available.
