Support Field Offices

[subdigital]

The API was just updated to include field offices for contacts. It currently looks like this:

                {
                    "area": "Senate",
                    "field_offices": [
                        {
                            "city": "Central Texas",
                            "phone": "512-916-5834"
                        },
                        {
                            "city": "East Texas",
                            "phone": "903-593-5130"
                        },
                        {
                            "city": "North Texas",
                            "phone": "214-599-8749"
                        },
                        {
                            "city": "South Texas",
                            "phone": "956-686-7339"
                        },
                        {
                            "city": "South/Central Texas",
                            "phone": "210-340-2885"
                        },
                        {
                            "city": "Southeast Texas",
                            "phone": "713-718-3057"
                        }
                    ],
                    "id": "TX-TedCruz",
                    "name": "Ted Cruz",
                    "party": "Republican",
                    "phone": "202-224-5922",
                    "photoURL": "http://www.cruz.senate.gov/files/images/OfficialPortrait.jpg",
                    "reason": "This is one of your two senators",
                    "state": "TX"
                }

We need a similar mechanism for choosing which number to call on the CallScriptViewController
