New description:
This patch implements algorithms for computing the Gromov hyperbolicity of
a graph. Although the worst case time complexity is in `O(n^4)`, the
proposed implementation performs quite well in practice. It has been used
on graphs with more than 10.000 vertices.

Comment:
I was not aware of this patch.
The dependency is fixed, as well as the #long time. I hope it is OK now.
