The second release of Bottleneck is faster, contains more functions, and supports more dtypes.

- Faster nanmean() for 2d, 3d arrays containing NaNs when axis is not None

## New functions

- nanargmin()

- nanargmax()

- nanmedian()

## Enhancements

- Added support for float32

- Fallback to slower, non-Cython functions for unaccelerated ndim/dtype

- Scipy is no longer a dependency

- Added support for older versions of NumPy (1.4.1)

- All functions are now templated for dtype and axis

- Added a sandbox for prototyping of new Bottleneck functions

- Rewrote benchmarking code
