Hi Andy,

This is my fault. I should have asked the list first: I bumped up the
Cython version to use typed
memoryviews<http://docs.cython.org/src/userguide/memoryviews.html>
.

My rationale was that we should be pretty conservative with older,
more-entrenched packages like numpy and matplotlib, but less conservative
with something that's rapidly evolving, like Cython.

I'm fine with converting morphological reconstruction to support Cython
0.15 if there's push back.

Cheers,
-Tony
