Overcomplete haar dictionary bug

[ghost]

HaarDictionary(n, k) return dictionary of size k^2 x n^2 instead of n^2 x k^2.
I think that there is a problem in haar function defined in dictionaries/utils.py - it only work for sampling_factor=None because tmp[i]=0 for i > n.

Unfortunately I couldn't find the exact definition of the Overcomplete Haar Dictionaries as used in the K-SVD literature. However, I found this Matlab script to generate a 8x21 Haar Dict:

I assume it would be possible to generalize this to the nxK case. I'll try to add it once I have the time.
