derecursion of create_star_3:
...
I remade a benchmark and finally when using boost::thread_specific_ptr,
using a std::vector is faster than the dedicated vector-class I previously
use.
I also retry using a tuple instead of a dedicated class to store variables
useful for the emulated recursion but tuple is (on my machine) slower.
benchmark results are the following (points are randomly taken in a sphere,
time is in seconds and is the mean of 10 idendical runs)

Remove recursive call of create_star_3:
...
--create an internally used vector that can reserve its size when constructed
--create an internally used class to store information required to emulated the call stack
--the stack used to emulate the call stack is a static thread-safe vector of the function (thus a memory overhead)
These choices have been made so that the running time of the triangulation is still the same.

I did it for 3D only because the degenerate 2D case should be
handled by the circulator anyway.
I did not add the test which explodes the call stack (in case we plug
the recursive version): too slow for a testsuite. But incident_...
methods are used everywhere in the code anyway.
