Add __getitem__ and __setitem__ to provide direct access to coordinates

Assuming

    p = geojson.Point((-115.81, 37.24))

If would be convenient to be able to write

    print(p[0])

rather than

    print(p['coordinates'][0])

Is this something you would consider?

I can send a PR.

You should also be able to do p.coordinates[0]. I don't think we need another way to get the coordinates. Thanks for the idea though!

[lafrech]

Yes, I noticed that. It's a bit better.

My data model has a "position" attribute which is a geojson.Point. Currently, I need to write

my_object.position.coordinates[0]

which I'd happily simplify into

my_object.position[0]

This is not really a big deal, and I guess I could monkey patch geojson geometries or just live with it.

There can be other properties on a Point besides coordinate, so I think it wouldn't be too obvious which one you're indexing into.

[lafrech]

Fair enough. I thought coordinates was the only list-like attribute, so it wouldn't be ambiguous.

Sorry for the noise.

All good, no worries! Definitely a good idea that was worth considering :)
