Add Akima Interpolation to Pandas

[dershow]

Currently Akima is not a valid interpolation method in Pandas. However scipy does have Akima1Dinterpolator. As Pandas uses SciPy for doing interpolation, adding the Akima method to pandas should be easy.

sure, requires scipy >= 0.14.0 though.

It looks like for the pchip interpolate that pandas just does a check to verify that it is there, and otherwise reports that scipy doesn't support it.
