Migration to Flask

Flask is a microframework

By convention, templates and static files are stored in subdirectories within the application's Python source tree, with the names templates and static respectively. This can be changed, you usually don't have to, especially, when getting started.

A Python web application based on WSGI has to have one central callable object that implements the actual application. In Flask this is an instance of the Flask class.
