HOG feature extraction

[Josh Warner]

Hi Manan,

First, that is a very old version of the package. Farther up the tree 
`version.py` states it's version 0.6.1 - we are currently shipping version 
0.11.3. I hope Python(X,Y) isn't still shipping 0.6.1. Before anything 
else, upgrade your scikit-image installation if needed.

Second, the test files is designed to test the package, not as direct 
examples of usage. They can be helpful to understand how files work, but 
realize they are unit tests. We run all files matching `test_*.py` in the 
repo using nosetests in our continuous integration builds. We don't want 
output from these; they are designed to pass if everything is well. So the 
fact that you don't get any output is working as intended, and reassuring. 
That means HOG is operating on your system.

The documentation for HOG is located 
here: http://scikit-image.org/docs/stable/api/skimage.feature.html#hog

I hope that helps set you on your way,

Josh
