A function for setting up aiohttp web server

Web server based on aiohttp library is, IMHO, more modern and flexible than others. So, as I use it pretty often, I decided to customize it for myself.

You can run aiohttp web server as simple as

from aiohttp_setup import aiohttp_setup

aiohttp_setup()

There are following features:

• static files are enable; the default directory where they are located is ./public directory;
• you can pass async services to the setup as tuples (start-function and stop-function);
• you can pass routes, that can be organized in separate module.

The function has no position parameter and some keyword-parameters:

def aiohttp_setup(host='localhost', port=8080, services=[], routes=None, 
        static_dir='public', index_file='index.html', root_path='/', 
        show_index=True):

I mean their names describes themselves, but, I hope to write some documentation in future :) .
