measuring the longest thread of a skeleton

[Juan Nunez-Iglesias]

Eyal, not naive at all, it's a reasonable expectation! Skeletonization and
related algorithms are a place where the library needs improving. If you
come up with a good solution, we can help you get it into the library. See
http://scikit-image.org/docs/stable/contribute.html .

Thanks!

Juan.
