Hello -

I'm quite new to CGAL and to Computational Geomtry, but I'm learning. 

I have an irregular flat (trianglar) mesh structure, and a complex, non 
self-intersecting polygon, and I would like to find all points of 
intersection between these two objects, as shown below:

Is there a CGAL package(?) that already does something like this? 

Thanks,

- Olumide
