Implementation of the algorithm for replacing faces in shape with new faces based on other surfaces - BRepOffsetAPI_PatchFaces.

The algorithm runs the steps similar to 3d Offset algorithm for Join type Intersection (intersection of the faces with neighbors for trimming of the faces by the adjacent faces).
