// .NAME vtkContourValues - helper object to manage setting and generating contour values
// .SECTION Description
// vtkContourValues is a general class to manage the creation, generation,
// and retrieval of contour values. This class serves as a helper class for
// contouring classes, or those classes operating on lists of contour values.
