        """
        Retrieve all major games played for a given week.

        Builds a URL based on the requested date and downloads the HTML
        contents before parsing any and all games played during that week. Any
        games that are found are added to the boxscores dictionary with
        high-level game information such as the home and away team names and a
        link to the boxscore page.

        Parameters
        ----------
        week : int
            The week number to pull games from.

            the games from the day specified in the 'date' parameter will be
            saved.
