Hi,

This question was asked before several times, and the answer is surprisingly
not possible. I wanted to verify that. 

Let's say I have an existing triangulation (e.g. .off), and I want to load
it into Triangulation_2. My objective is to take advantage of the methods in
Triangulation_2, such as point location (which can be done with AABB tree as
well). 

There is an overloaded operator>>, which reads only points, as far as I can
see, and ignores the connectivity.

So the only way, I can see, is to construct a constrained triangulation
(constraining the desired connectivity), and deleting redundant faces.

Is this correct? If it is, please consider making the Triangulation_2
construction more versatile.
