1.The algorithm searching the section in the corner (ChooseSection) is modified to be able to find simple cases with rather big tolerance. 2. The constructor of BRepFill_Section is modified: now it removes locations in the shape of section like it was done in BRepFill_Pipe. 3. Correction of U-edges by Same Parameter has been added to the method BRepFill_Sweep::Build.
