General architecture notes
This is a standalone Eye-Fi Server that is designed to take the place of the Eye-Fi Manager.
Starting this server creates a listener on port 59278. I use the BaseHTTPServer class included
with Python. I look for specific POST/GET request URLs and execute functions based on those
URLs.
