[SciPy-User] [ANN] Bottleneck 0.4.0

[Keith Goodman]

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

The fourth release of Bottleneck contains new functions and bug fixes.
Separate source code distributions are now made for 32 bit and 64 bit
operating systems.

New functions:
- rankdata()
- nanrankdata()

Enhancements:
- Optionally specify the shapes of the arrays used in benchmark
- Can specify which input arrays to fill with one-third NaNs in benchmark

Breaks from 0.3.0:
- Removed group_nanmean() function
- Bump dependency from NumPy 1.4.1 to NumPy 1.5.1
- C files are now generated with Cython 0.14.1 instead of 0.13

Bug fixes:
- #6 Some functions gave wrong output dtype for some input dtypes on 32 bit OS
- #7 Some functions choked on size zero input arrays
- #8 Segmentation fault with Cython 0.14.1 (but not 0.13)
