[SciPy-Dev] wrapped FITPACK's `sphere.f`

[Andreas H.]

Hi,

I just wrapped FITPACK's `sphere.f` for scipy.interpolate, to make
interpolation/smoothing in spherical coordinates possible.

Here's the pull request:

Sorry for not discussing this here earlier, I just now found out about the
"Contributing to SciPy" guide.

Cheers,
Andreas.
