OutIterator BarycentricWeights_2::operator()  (  const Point_2 &  query, 
OutIterator  w_begin  
) 
fills a destination range with 2D generalized barycentric weights computed at the query
point with respect to the vertices of the input polygon.
OutIterator  a model of OutputIterator whose value type is FieldNumberType 
The number of computed weights is equal to the number of polygon vertices.
