Address component parsing

And if you just want to parse an individual address into its components:

>>> client.parse('1600 Pennsylvania Ave, Washington DC')
{
    "address_components": {
        "number": "1600",
        "street": "Pennsylvania",
        "suffix": "Ave",
        "city": "Washington",
        "state": "DC"
    },
    "formatted_address": "1600 Pennsylvania Ave, Washington DC"
}

The return value is simple enough to us as the returned dictionary.
