/**
 * This widget displays a TV style banner showing the standings of your class.
 * Designed to be used as an overlay with OBS.
 * 
 * By default, the session type is displayed as the title.
 * The default sponsor is SIMRacingApps.
 * To change either, create a file called "StandingsBanner.json" in the "Documents/SIMRacingApps" folder 
 * with the following entries.
 * <pre>
 * {
 *   "title":            "DAYTONA 500",
 *   "fontSize":         "100%",
 *   "sponsorImageUrls": ["Sponsors/Sponsor1.png","Sponsors/Sponsor2.png","sra"],
 *   "sponsorSeconds":   [60,120,60]
 * }
 * </pre>
 * In the example, the sponsor logos is an array of files that are stored in the "Documents/SIMRacingApps/Sponsors" folder.
 * The ratio of a sponsor file should be 4x1. The default window size calculates that to be 200x50 pixels, but it will scale up and down.
 * Each sponsor can have their own display time using the seconds array.
 * The first sponsor will be displayed for 60 seconds, the second for 120 seconds, then start over.
 * You can add more sponsors and seconds to display as needed.
 * Any image that cannot be found will be replaced with the stock SRA logo.
 * <p>
 * Example list of the files.
 * <pre>
 *    Documents\SIMRacingApps\StandingsBanner.json
 *    Documents\SIMRacingApps\Sponsors\Sponsor1.png
 *    Documents\SIMRacingApps\Sponsors\Sponsor2.png
 * </pre>

 * Example:
 * <p><b>

 * @ngdoc directive
 * @name sra-standings-banner
 * @param show-short-name Set to true to show the short name. Default is false.
 * @param show-team-name Set to false to not show the team name. Default is true.
 * @param {integer} data-sra-args-interval The interval, in milliseconds, that this widget will update from the server. Default is 500.
