Provides a Python-compatible interface for the Apple Remote.
Requires this modified version of iremoted: http://github.com/swinton/iremoted.

Usage:
1. Install iremoted from http://github.com/swinton/iremoted along with this Python module.
2. Construct your source code like so:

from iremote import IRemote

def my_iremote_handler(event):
    if event == IRemote.NEXT:
        # Next button pressed
        # ...

iremote = IRemote()
iremote.add_listener(my_iremote_handler)
iremote.start()
