Non-local means denoising

[Emmanuelle Gouillart]

Hi Juan,

yes, it's been a long time :-) (I took a new job in September and it's
been pretty hectic since then!).

My implementation is indeed 3-D. I'll start working on a PR this week-end
then! For 3-D images the code is pretty slow due to the large size of the
data, but I also have a pycuda + cuda implementation written by my PhD
student William. You'll tell me if you're interested!

Cheers,
Emmanuelle
