initial framework and simple test page

Structure:
- hanlders is where all the handlers for the url/uri's go
- templates is where any templates we need to, whether this is html or not

- Don't touch app.yaml or main.app
-  handlers/Handlers.py is where all the url/uri's go
-  handlers/IndexHandler.py is a simple handler for an html template
-  handlers/MainHandler.py is where we will put authentication and each handler will implement a class from this file
-  templates/index.html is a simple html page. Just used to test.
