Standardize JSON response on arrays or objects

[waldoj]

The API is inconsistent in its use of arrays and objects. For example, from the law method:

"references": [
    {
        "id": "12528",
        "section_number": "22.1-29.1",
        "catch_line": "Public hearing before appointment of school board members.",
        "url": "http://vacode.org/22.1-29.1/"
    },
    {
        "id": "12533",
        "section_number": "22.1-34",
        "catch_line": "Application of article.",
        "url": "http://vacode.org/22.1-34/"
    }
],
"related": {
    "0": {
        "id": "7469",
        "catch_line": "Department of education.",
        "section_number": "15.2-531",
        "url": "/15.2-531/"
    },
    "1": {
        "id": "7618",
        "catch_line": "Department of education.",
        "section_number": "15.2-837",
        "url": "/15.2-837/"
    },
}

references is an array, while related is an object, with the former unenumerated, the latter enumerated. This is confusing, and makes the data difficult to parse. Fix this in a v1.1 of the API.
