Added skeletal API, cannot take input

I wrote a simple Python wrapper to the Yelp API. You can pull it from my fork to your repository, which is the master branch for this project. 

(If any terminology is unclear, read the GitHub FAQs. If it is still unclear, then ask me.)

 1. Pull the code to your GitHub repo; this 'updates' your repo.
 2. Update your remote copy by pulling your GitHub repo to your remote branch
 3. Step into the folder on your computer and run `python test.py`
4. Modify line 16 according to the Yelp documentation. Currently it searches for bars in NYC. 

Make sure that you understand the structure of the output:
 1. The output is in _JSON format_. 
 2. The output contains _fields_ that the Yelp documentation further describes.
 3. You may have to install git on your computer to run commands like `git clone` or `git add` from the command line.
