    Description :
    ____________

    The ARETE operator constructs a mesh composed of SEG2 elements
    which represent the sharp edges of a three-dimensional mesh.
    In this operator, an edge is considered to be sharp whenever
    the difference of angle between the normals of the adjacent 
    facets is greater than a boundary TETA equalling 20 degrees by
    default.
