routes.py: Create a new route /delete similar to /population. delete create a DeleteForm object, and on a button click, it checks whether the city name input in the form is in the 'cities' dictonary. If it is, it deletes it from cities. The route should then redirect to the view route. The render_template sends delete.html as a argument. Remember to import DeleteForm at the top of routes.py.

Here is what I have so far. Need help on the deletion part
