Hello, 

I am new to Boost Geometry, and I have a question to ask if I could use it
or not.
 
I have several non-ordered polygons, it is not known that which polygon are
external, and which polygon are internal holes. Is there any way to classify
which polyogns are holes to what polygons, and get the ordered polygons so
that I know which are holes and which are external polygons?
 
Thanks
