I don't know if and when I'll have occasion to use this stuff, but I'm glad it's there. Nice work, Pauli!

One comment: the name "griddatand" looks odd to my eyes, my mind wants to group it as "datand". I only mention this because it might slip past someone who's looking for "griddata" (also, does np.lookfor match partial words?). I don't really have a suggestion of another name though. "ndgriddata"? Then griddata looks a bit more separate, and it'd match scipy.ndimage.
