[SciPy-User] [ANN] Bottleneck 0.3

[Keith Goodman]

Bottleneck is a collection of fast NumPy array functions written in
Cython. It contains functions like median, nanmedian, nanargmax,
move_mean.

The third release of Bottleneck is twice as fast for small input
arrays and contains 10 new functions.

Faster:
- All functions are faster (less overhead in selector functions)

New functions:
- nansum()
- move_sum()
- move_nansum()
- move_mean()
- move_std()
- move_nanstd()
- move_min()
- move_nanmin()
- move_max()
- move_nanmax()

Enhancements:
- You can now specify the dtype and axis to use in the benchmark timings
- Improved documentation and more unit tests

Breaks from 0.2.0:
- Moving window functions now default to axis=-1 instead of axis=0
- Low-level moving window selector functions no longer take window as input

Bug fix:
- int input array resulted in call to slow, non-cython version of move_nanmean
