    "endDateTime": "2016-11-28T16:05:00.000Z",
    "location": "Theatre,Theatre Lobby"
}

    - endDateTime: end date/time string of event (JS date string)

/* ENDPOINT: GET /athleticsCalendar
--------------------------
A scraper for the athletics calendar, including practices and games.
Responds with an object with the following format:

{
    "games": [
        ...
    ],
    "practices": [
        ...
    ]
}

Each array contains athletics event objects in chronological order for athletics
games and practices scraped from the school website.  The information scraped
for games and practices is slightly different, however.  The games events have
the following format:

{
    "month": "Sep",
    "date": 28,
    "year": 2016,
    "team": "Boys' Varsity Soccer",
    "opponent": "Other School"
    "time": "2016-11-28T15:45:00-05:00",
    "location": "Back Field",
    "isHome": true,
    "result": null,
    "status": "CANCELLED"
}

Every game event object is guaranteed to have the following fields:

    - month: an abbreviated name for the event month
    - date: the numeric date
    - year: the numeric year
    - team: the school team competing
    - isHome: boolean whether or not this is a home game

Additionally, a game event object may have the following fields:

    - opponent: the opposing team name
    - time: a datetime string
    - location: the name of the game's location (NOT necessarily address)
    - result: "Win" or "Loss" or another string indicator of game result
    - status: "CANCELLED" or another string indicator of game status

The practices events have the following format (a subset of the game object):

{
    "month": "Sep",
    "date": 28,
    "year": 2016,
    "team": "Boys' Varsity Soccer",
    "time": "2016-11-28T15:45:00-05:00",
    "location": "Back Field",
    "status": "CANCELLED"
}

All fields in a practice object are the same as their corresponding fields in a
game object.
