The Surface from BRepAdaptor allows to use a Face
of the BRep topology look like a 3D surface.
It has the methods of the class Surface from
Adaptor3d.
It is created or initialized with a Face. It takes
into account the local coordinates system.
The u,v parameter range is the minmax value for
the restriction, unless the flag restriction is
set to false.
