How to extrude a surface from a curve?

Hi, @tpaviot 

I am just a new comer to opencascade.

I am trying to add the ``Support`` of an ``anEdge`` in ``BRepFill_Filling.Add``. And I would like to extrude the edge to get the supporting surface. But I have not found a function to do so.

Is there any function to use?

Thanks!
