Python library for connecting to and controlling the Logitech Harmony Link

As the harmony protocol is being worked out, notes are in PROTOCOL.md.

• Authentication to Logitech's web service working.
• Authentication to harmony device working.
• Querying for entire device information
• Sending a simple command to harmony device working.

To query your device's configuration state:

PYTHONPATH="." python harmony --email user@example.com --password pass \
    --harmony_ip 192.168.0.1 show_config

For full argument information on the command-line tool:

PYTHONPATH="." python harmony

• Figure out how to detect when the session token expires so we can get a new one.
• Figure out a good way of sending commands based on sync state.
• Is it possible to update device configuration?
