Unit test failure is on the cython side when window=1. float64 dtype is returned even when input is float32.
Make single source distribution instead of separate 32 and 64 bit versions. Closes #16.
Faster version of scipy.stats.ss
This functon is only used in the slow version of rankdata: bn.slow.rankdata() and bn.slow.nanrankdata().
Bug fix will come in a separate commit so that unit test failures produced by this commit will demonstrate the bugs.
The low-level functions nanstd_3d_int32_axis1 and nanstd_3d_int64_axis1, called by bottleneck.nanstd(), wrote beyond the memory owned by the output array if arr.shape == 0 and arr.shape > arr.shape, where arr is the input array.
