[SciPy-Dev] Graph shortest path

Hello,
A while ago in scikit-learn we implemented an efficient cython graph
shortest-path search using both Dijkstra's algorithm and the
Floyd-Warshall algorithm with Fibonacci heaps. Currently this is
well-hidden in the scikit-learn utils:
https://github.com/scikit-learn/scikit-learn/blob/master/sklearn/utils/graph_shortest_path.pyx
This is the kind of basic algorithm that I think belongs in scipy rather
than scikit-learn. I know that some developers have been thinking about
graph tools for scipy: are there ideas about whether/where the shortest
path search would fit in scipy?
Thanks
Jake
