Python Bottleneck download

v0.7 [Oct 18, 2013]
- bn.rankdata() is twice as fast (with input a = np.random.rand(1000000))
- C files now included in github repo; cython not needed to try latest
- C files are now generated with Cython 0.19.1 instead of 0.16
- Test bottleneck across multiple python/numpy versions using tox
- Source tarball size cut in half
Bug fixes
- move_std, move_nanstd return inappropriate NaNs (sqrt of negative #)
- make test fails on some computers
- scipy optional yet some unit tests depend on scipy
- nanstd([1.0], ddof=1) and nanvar([1.0], ddof=1) crash
