Hi Juan Carlos,

About this inf vertex, you should carefully read the documentation. It 
is a very helpful concept
when dealing with the vertices that are "on the outside" of the 
triangulation (more precisely,
on the convex hull), but you have to be careful about this vertex, and its
cells and edges. Notice there are e.g. iterators over finite vertices in 
order to avoid this one.

Best,

Daniel
