Implement nonlinear anisotropic filtering for noisy images #70

A sophisticated image smoothing method might be useful to preprocess very noisy images. Considered options are:

Edge enhancing diffusion
Coherence enhancing diffusion

This is now implemented in devel branch. I have tweaked the referenced algorithms a bit in the way I have understood, mainly on the eigen-value compositions part.
