Adding a denoising example using Fields of Experts.
We have permission from Stefan Roth to use the coefficients from his
Matlab toolbox. They have been added as *.foe files.

+The *.foe files contain coefficients provided by Stefan Roth, who agreed to
+release them under a BSD license. See his home page:
+
+ http://www.gris.informatik.tu-darmstadt.de/~sroth/research/foe/index.html
+
+The coefficients in the *.foe files have been obtained by extracting the
+matrices from the MATLAB files and performing matrix multiplication.
+
+The format of the files is ASCII:
+ <s = filter size> <K = number of filters>
+ <alpha_1> ... <alpha_K>
+ <f_1,1> ... <f_1,s^2>
+ ...
+ <f_K,1> ... <f_K,s^2>
