Title: Nearest neighbour indexing no longer loads the data.

Fixes a question raised at http://stackoverflow.com/questions/18313916/interpolate-cube-data-to-a-given-list-of-points about nearest neighbour interpolation without actually loading the data first.

I haven't looked at whether nearest neighbour regridding can do this, but in principle, that too should be perfectly possible.
