// .NAME vtkIntegrateFlowThroughSurface - Integrates vector dot normal.
// .SECTION Description
// First this filter finds point normals for a surface.  It
// Takes a point vector field from the input and computes the
// dot product with the normal.  It then integrates this dot value
// to get net flow through the surface.
