 for edges, vertices and faces. So testing i.e. whether a face is a boundary
 face is quite simple using OpenMesh::PolyConnectivity::is_boundary().<br />
 
+\note You can iterate along boundaries by using the next_halfedge_handle(). If you are on a boundary, the next halfedge is guaranteed to be also a boundary halfedge.

 So for each type we can make use of one of the following functions:
