AIRPort city name resolver. And back.

This is how you use it:

$ pip install irp
$ export IATACODES_API_KEY="..."  # Get it for free at iatacodes.org
$ ipython

In [1]: from irp import get_airports, get_name

In [2]: list(get_airports('Portland'))
Out[2]: [('PDX', 'US'), ('PTJ', 'AU'), ('PWM', 'US')]

In [3]: list(get_airports('Portland, US'))
Out[3]: [('PDX', 'US'), ('PWM', 'US')]

In [4]: list(get_airports('PDX'))
Out[4]: [('PDX', 'US')]

In [5]: list(get_airports('Isiro'))
Out[5]: [('IRP', 'CD')]

In [6]: get_name('IRP')
Out[6]: 'Isiro'
