+// .NAME vtkVolumeContourSpectrumFilter - compute an approximation of the
+// volume contour signature (evolution of the volume of the input tet-mesh
+// along an arc of the Reeb graph).
+// .SECTION Description
+// The filter takes a vtkUnstructuredGrid as an input (port 0), along with a
+// vtkReebGraph (port 1).
+// The Reeb graph arc to consider can be specified with SetArcId() (default: 0).
+// The number of (evenly distributed) samples of the signature can be defined
+// with SetNumberOfSamples() (default value: 100).
+// The filter will first try to pull as a scalar field the vtkDataArray with Id
+// 'FieldId' of the vtkUnstructuredGrid, see SetFieldId (default: 0). The
+// filter will abort if this field does not exist.
+//
+// The filter outputs a vtkTable with the volume contour signature
+// approximation, each sample being evenly distributed in the function span of
+// the arc.
+//
+// This filter is a typical example for designing your own contour signature
+// filter (with customized metrics). It also shows typical vtkReebGraph
+// traversals.
