/**
 * This class is responsible for all formatting of dates. There are 2 implementations available, the `CalendarNativeDateFormatter` (default) which will use the <a href="https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Intl" target="_blank">Intl</a> API to format dates, or there is the `CalendarMomentDateFormatter` which uses <a href="http://momentjs.com/" target="_blank">moment</a>.
 *
 * If you wish, you may override any of the defaults via angulars DI. For example:
 *
 * ```
 * import { CalendarDateFormatter, DateFormatterParams } from 'angular-calendar';
 *
 * class CustomDateFormatter extends CalendarDateFormatter {
 *
 *   public monthViewColumnHeader({date, locale}: DateFormatterParams): string {
 *     return new Intl.DateTimeFormat(locale, {weekday: 'short'}).format(date); // use short week days
 *   }
 *
 * }
 *
 * // in your component that uses the calendar
 * providers: [{
 *   provide: CalendarDateFormatter,
 *   useClass: CustomDateFormatter
 * }]
 * ```
