// .NAME vtkAreaContourSignatureFilter - compute an approximation of the area
// contour signature (evolution of the area of the input surface along an arc of
// the Reeb graph).
// .SECTION Description
// The filter takes a vtkPolyData 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 vtkPolyData, see SetFieldId (default: 0). The filter will
// abort if this field does not exist.
//
// The filter outputs a vtkTable with the area 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.
