Title: bag of words in python modular (for GSOC)

Hi,

I am submitting a patch, a python file named features_bagofwords_sift.py
It implements the bag of words approach.

As Alexander Binder, pointed out in the proposal, this methods provides a relaxation in the fixed feature size requirements. Although this is just a simplified version, were in I assume the image to contain a single path in order to calculate the histogram. Usually the image is divided into 4 patches and histograms from each patch in concatenated.

I will be applying for the last two ideas (latent SVM and the bag of words approach)

Cheers!
