class FaceAreaBuilder from BOP inherits Area2dBuilder from BOP

    ---Purpose: 
    -- The FaceAreaBuilder algorithm is used to construct Faces from a LoopSet,
    -- where the Loop is the composite topological object of the boundary,
    -- here wire or block of edges.
    -- The LoopSet gives an iteration on Loops.
    -- For each Loop  it indicates if it is on the boundary (wire) or if it
    -- results from  an interference (block of edges).
    -- The result of the FaceAreaBuilder is an iteration on areas.
    -- An area is described by a set of Loops.
