// .NAME vtkIntegrateAttributes - Integrates lines, surfaces and volume.
// .SECTION Description
// Integrates all point and cell data attributes while computing
// length, area or volume.  Works for 1D, 2D or 3D.  Only one dimensionality
// at a time.  For volume, this filter ignores all but 3D cells.  It
// will not compute the volume contained in a closed surface.
// The output of this filter is a single point and vertex.  The attributes
// for this point and cell will contain the integration results
// for the corresponding input attributes.
