Title: Manhattan distance function

I created the file *distances/manhattan.py* that implements the [Manhattan distance function](http://en.wikipedia.org/wiki/Taxicab_geometry).
I needed it for my own work, but thought it might be useful to the NearPy library in general.
Let me know if anything needs to be changed or added.
