[vtkusers] Extract subset of a surface by edges

[Bill Lorensen]

Off the top of my head... the following might work:

vtkPolyDataNormals will create new edges based on a feature angle. Follow that by a vtkPolyDataConnectivity.

Is there any filter ready for that, or is there any pipeline that I should construct in order to achieve the goal?  For example, for a cube in a single surface, I should extract 12 edges, and I would like to obtain 6 faces of that cube.
