 I am trying to find a "fast" way to do the following:

Given an object t of type Triangulation_2  create a Polyhedron_3 which has
the same vertex and edge set
as t.

 Looking at the BGL interface for CGAL, I was thinking to use  either the
copy_graph command with a custom
VertexCopier function or use the Boost DFS algorithm on the Triangulation
while handling the addition of edges
on the Polyhedron with a customized visitor.  But I'm not sure if this is
supposed to work since there doesn't
seem to be some way to create a vertex in your target graph (here: the
Polyhedron) so that you can set any of 
the member values of this vertex (e.g. to enter the coordinates of the 3D
point associated with this vertex ).
