// .NAME vtkPolyPlane - Implicit function that is generated by extrusion of a polyline along the Z axis
// .SECTION Description
// vtkPolyPlane is, as the name suggests, an extrusion of a vtkPolyLine.
// The extrusion direction is assumed to be the Z vector. It can be used in
// combination with a vtkCutter to cut a dataset with a polyplane.
// vtkPolyPlane is a concrete implementation of the abstract class
// vtkImplicitFunction.
//
// .SECTION ToDo
// Generalize to extrusions along arbitrary directions.
