python3;added test file

[robeartoe]

Made it so it works with Python3. Added test file to test both API and Website. Changed Website portion, to make it easier add webpages and things later on. Changed range_end to always have the correct number without having to manually change everytime.

I think it has unnecessary dependencies in requirements.txt
See if you can fix those.
Also is flask_restful being used in your code?

Oh you're right! It had added more outside of my virtualenv. How odd. Anyways, I fixed that. I only added the requests module and its dependencies.

Yes, flask_restful is still being used, it's being used for the '/api' route. I replaced the '/' route to use Flask instead of flask_restful. Since I noticed you might want to develop a website in the future, setting up the '/' route with Flask is essential, because flask_restful isn't a good tool for delivering webpages and things.

Sorry I'm still kind of new to pull requests and doing all this. So I hope I'm doing this right.
