DOC: remove docstring from UnivariateSpline.__init__

same for InterpolatedUnivariateSpline and LSQUnivariateSpline.
These simply duplicated the class docstrings.
DOC: improve the docstrings of *UnivariateSpline classes

Tweak examples to make plots actually render.
DOC: add a nan masking example to the UnivariateSpline docstring

BUG: misc: Ensure that the 'size' argument of PIL's 'resize' method is a tuple.

In Pillow 2.5.3, the code for the 'resize' function has a statement of the
form 'if self.size == size: ...'.  The expectation is that 'self.size' and
'size' are tuples.  If 'size' is a numpy array, the comparison raises
'ValueError: The truth value of an array with more than one element is
ambiguous.'

This commit ensures that the 'size' argument passed to the 'resize' method
is a tuple.

Closes gh-4032.
MAINT: misc: Remove unused imports and do some PEP8 clean up in pilutil.py.
BUG: stats: Refactor argument validation to avoid a unicode issue.

Fixes the handling of a unicode argument to the binned statistics
functions.

ENH Addeded Fisher's method and Stouffer's Z-score method closes #3092
Refactor stats.combine_pvalues, add docs and tests

Refactored Fisher's method and Stouffer's method into a single method called
stats.combine_pvalues. Added documentation for this method, and added tests for
weighted Stouffer's method. Minor naming and style fixes.
