Hi,
I installed ELSA and all it's requirements as stated in the get_started.pdf. After running all tests 4 out of 5 are successful. The other gives me following error:

/usr/lib/python2.7/dist-packages/matplotlib/cbook.py:137: MatplotlibDeprecationWarning: The matplotlib.delaunay module was deprecated in version 1.4. Use matplotlib.tri.Triangulation instead.

I attached node 6 with degree 1 to node 17
I attached node 18 with degree 1 to node 0
..The following sectors do not have any navpoint left: [4]

I add a navpoint at the centroid for them.
I add also some links with the closest points of neighboring sectors.
G.neighbors(sec) [1, 3, 6]
