Hi everybody

I have segments that i want to connect. Sometimes my segments are 
totally connected
and sometimes it is an open contour.
I tried to use Arrangement_2 class to find the contour. I build my 
arrangement from segments and
when i am travelling the halfedges, i have some halfedges with same 
source and target vertex.
Is it possible? and is it possible to remove this kind of halfedges at 
construction?
Thank you very much
Cyril
